Hey there!
In order to solve this equation, you need to first simplify and take the absolute value:
x+2+x+2-x+5
Now you need to simplify
x+9
So, the rewritten form of the equation is x+9

REPEATED REASONING What happens to the circumference and the area of a circle when you double the radius? triple the radius?
double the radius:
circumference =
times larger,
area =
times larger;
triple the radius:
circumference =
times larger,
area =
times larger
also explain how u did it for brainliest if its right
Answer: So when you double the radius, the area goes up by 4 times because 2 squared is 4. The area will always go up by the square of how much the radius goes up. By contrast, the circumference will only double -- from 12.56 to 25.12 because you do not square the radius (or diameter) -- you just multiply it by pi.

Dalia buys a winter jacket at a used clothing store that costs $30. She lives in Idaho, where the sales tax is 6%.
Write an equation that represents the total cost, c, of any item bought in Idaho whose price is p
Answer:
c = 0.06p + p
Step-by-step explanation:
hope this helped
An equation that represents the total cost, c, of any item bought in Idaho whose price is p is c = 1.06p.
What is an Equation?An equation is the statement of two expressions located on two sides connected with an equal to sign. The two sides of an equation is usually called as left hand side and right hand side.
Given that,
Cost of the winter jacket = $30
Sales tax = 6%
Total cost of the winter jacket = 30 + (6% × 30)
= 30 + 1.8
= $31.8
If the total cost of any item is c whose price is p,
c = p + (6% × p)
c = p + 0.06p
c = 1.06p
Hence the required equation is c = 1.06p.

Answer:
x=10
Step-by-step explanation:
so your given an angle, 110, and another with an equation, 8x+30, which happens to be vertical to 110 degree angle meaning they are equal, so they both are equal to 110 now how do you solve for x? you simply reverse the equation that x is in, so you subtract 110-30=80, then divide by 8 giving you 10, so x=10.
Answer:
X = 10, because of the second angle's equation. 8x + 30 hints the solution. 110 - 30 is 80, and 80 / 8x In this case, x can be represented as itself is 10

Classify Each triangle by its angle and sides.
Answer:
8. Scalene 9. Isosceles
Step-by-step explanation:
8) Acute Scalene
9) Right Isosceles
Step-by-step explanation:Triangles can be classified in 3 ways based on their angles: acute, obtuse, and right. There are 3 ways to classify based on sides: scalene, isosceles, and equilateral.
Definitions
Acute - a triangle with 3 acute angles (angles under 90 degrees)
Obtuse - a triangle with 1 obtuse angle (angle greater than 90 degrees)
Right - a triangle with 1 right angle (90-degree angle)
Scalene - a triangle with sides of all different lengths
Isosceles - a triangle with 2 equal sides and angles
Equilateral - a triangle with 3 equal sides
Question 8
From the 2 angles we are given, we can tell that all of the angles are different. This must mean that the sides are also different. Since the sides are different, this must be a scalene triangle. Additionally, the missing angle is 100 degrees; thus, it must be an obtuse triangle.
Question 9
The marks on the 2 sides mean that these lines are equal. Therefore, it must be an isosceles triangle. One of the angles is marked with a box. This means that the angle is 90 degrees. So, it is a right triangle.
State the reason why K = M
Given:
KLMN is a parallelogram.
Answer:
They both are a 90 degree angle.
For the parallelogram KLMN, opposite angles K and M are equal.
What is Parallelogram?Parallelogram are type of quadrilateral in two dimensional geometry which has four sides, four vertices and four angles where opposite sides are equal. They also have the two pairs of sides parallel to each other. These sides are opposite sides.
The sum of the adjacent angles of the parallelogram is equal to 180 degrees and the sum of all angles is equal to 360 degrees. Also the opposite angles are equal.
Given that KLMN is a parallelogram.
Here K and M are opposite vertices and also L and N are opposite vertices.
In a parallelogram, we know that measure of opposite angles will be equal. So here, measure of angles K and M are equal.
Therefore, since angles K and M are opposite angles of the parallelogram, they are equal.

Step-by-step explanation:
Kitten:
2 times in the morning and 2 times in the evening = 4 times per day
That means Ariane feeds her kitten 4k grams of food per day.
Dog:
1 time in the morning and 1 time in the evening = 2 times per day
That means Ariane feeds her dog 2d grams of food per day.
Answer:
If you find the total, you have to add the kitten's food per day and the dog's food per day. That is 4k + 2d, which is the same as choice B.
We can break 4k into 2k + 2k. We can also break 2d into d + d. We can write that as 2k + 2k + d + d. That equals the same as choice C, making it a correct choice.

This figure consists of a rectangle and semicircle.
What is the area of this figure?
Use 3.14 for π.
A shape made up of a rectangle of the left and a semicircle on the right. The rectangle has a width of 15 meters and a height of 12 meters.
Enter your answer to the nearest hundredths place in the box.
Question 5 options:
Step-by-step explanation:
l = 12 metres
b = 15 metres
diameter of semicircle = length = 12 m
radius = 12/2 = 6 cm
area of the figure = area of rectangle + area of semi circle
= l × b + πr²
= 12 × 15 + 3.14 × 6²
= 180 + 113.04
= 293.04 m²
The perimeter of the figure is 60.84 meters.
What is a rectangle?A rectangle is a quadrilateral with all four interior angles 90°.
Given that, the width and height of the rectangle are 15 meters and 12 meters respectively.
Note that the diamter o he semicircel is 12 meters.
The radius of the semicircle is:
12/2
= 6 meters
The perimeter of the figure is given by:
15 + 12 + 15 + π(6)
= 42 + 3.14×6
= 60.84
Hence, the perimeter of the figure is 60.84 meters.

Can you help me find the formula for this shape?
Dylan loves reading. He went to buy books from a bookstore. A school bag and 3 books cost $180. A school bag and 5 books cost $270. How much did each book cost?
School bag _ y
book _ x
system:
y+3x=180
y+5x=270
y=180-3x (and we put that instead of 'y' in the second equation)
(180-3x)+5x=270
180+2x=270
2x=90
x=45
so one book costs $45
and school bag:
y+3×45=180
y+135=180
y=180-135
y=45
Answer:
Each book costed 45$.
Step-by-step explanation:
Let x represent the price of a school bag and y represent the price of a book.
we get the following system of equations:
x+3y=180 (equation 1)
x+5y=270 (equation 2)
using equation 1: x=180-3y
then we substitute x in equation 2 in order to find y:
180-3y+5y=270
180+2y=270
2y=270-180=90
y=90/2=45
and we know that y represents the price of a book, so each book costs 45$.

Select all of the equations that are equivalent to `3x+45=180`.
A. 3 (x + 45) = 180
B. 3 (x + 15) = 180
C. 3 (x + 15) = 60
D. x + 15 = 60
E. 3x = 135
Answer:
Option B and Option D
Step-by-step explanation:
B = 3*x = 3x, 3*15 = 45.
D=3* x + 15.
3x = 135 and x + 15 = 60 are the equations that are equivalent to 3x+45=180
What is Equation?Two or more expressions with an Equal sign is called as Equation.
We have to solve the equation 3x+45=180
Now isolate x on one side of the equation.
We can do this by subtracting 45 from both sides, giving us 3x=135, and then dividing both sides by 3 to get x=45.
Therefore, the equivalent equations are:
3x = 135
x + 15 = 60
Hence, 3x = 135 and x + 15 = 60 are the equations that are equivalent to 3x+45=180
