solve: 5 (x+2) +2x
make sure to show your work
Answer:
5 (x+2) +2x is equal to 7x + 10
Step-by-step explanation:
To find the value of this equation you would have to apply the distributive property by changing 5 (x+2) to 5x +10. (When applying the distributive property you will always multiply the numbers in the parentheses by the number on the left of it). Then you would combine like terms by adding 2x and 5x together. You will then have 7x + 10.
Step-by-step explanation:
1.) Distribute = 5x+10
2.) Collect Like-Terms = 5x & +2x
3.) Add 5x and +2x , which = 7x
Now you have your answer, which is: 7x + 10.
I hope this helped.
Which of the following variable expressions would represent the area of a rectangle if its length was represented by x+5 and its width was represented by x-2?
x[tex]x^{2} +3x+10\\
x^{2} +3x-10\\
x^{2} -10x+3\\
x^{2} -10[/tex]
Answer:
B
Step-by-step explanation:
Remember that the area of a rectangle is given by the formula [tex]A=lw[/tex].
We know that the length is [tex](x+5)[/tex] and the width is [tex](x-2)[/tex]. Therefore, the area will be:
[tex]A=(x+5)(x-2)[/tex]
Expand. Use the Distribute Property. This yields:
[tex]A=(x+5)(x)+(x+5)(-2)[/tex]
Multiply:
[tex]A=(x^2+5x)+(-2x-10)[/tex]
Combine Like Terms:
[tex]A=x^2+(5x-2x)-10\\A=x^2+3x-10[/tex]
Therefore, our answer is B.
Help it’s due tomorrow I’ll mark you as the brainless but please help
Answer:
The slope of a line is
[tex] \frac{y2 - y1}{x2 - x1} [/tex]
Get 2 points off each line
(x1, y1)
(x2, y2)
And sub them into the formula.
The y intercept is where the line cuts the y axis (the vertical line)
From what I can make out the y intercept for the first part in question 12 is (0,-2) and for the third part is (0,0) but I can't see the second one.
It might help if you took a clearer photograph I'm so sorry but I can't really see it.
If the infinite curve y = e−4x, x ≥ 0, is rotated about the x-axis, find the area of the resulting surface.
Answer: the area of the resulting surface is π/16 [ 4√(17) + In( 4 + √( 17)) ]
Step-by-step explanation:
Given that;
y = e^(-4x), x ≥ 0
then, dy/dx = -4e^(-4x)
now, √( 1 + (dy/dx)² ) = √( 1 + ( -4e^(-4x))²) = √( 1 + 16e^(-8x)
so the surface area of the surface obtaining by rotating the curve y = e^(-4x) on ( 0, ∞ ) about x-axis is,
S = ₀∫^∞ 2πy √( 1 + (dy/dx)² ) dx
S = ₀∫^∞ 2πe^(-4x) . √( 1 + 16e^(-8x) dx
S = 2π. ₀∫^∞ e^(-4x) . √( 1 + 16e^(-8x) dx
so LET 4e^-4x = u ⇒ -16e^(-4x) dx = du
⇒e^-4x dx = du/ -16
so whenx = 0, then u =4 and when x → ∞ then e^(-4x) → 0 so u →0
therefore
S = 2π ₄∫⁰ √(1 + u²) . du/-16
= π/8 ₀∫⁴ √(1 + u²) . du
= π/8 [ u/2√(1 + u²) + 1/2 In ( u + √( 1 + u²) ]₀⁴
WE MAKE USE OF
∫√( a² + u²) du = u/2√(a² + u²) + a²/2 In ( u + √( a² + u²)) + C
so
= π/8 [ 4/2√(1 + 16) + 1/2 In ( 4 + √( 1 + u16 ]
= π/8 [ 2√(17) + 1/2 In ( 4 + √( 17)) ]
= π/16 [ 4√(17) + In( 4 + √( 17)) ]
therefore the area of the resulting surface is π/16 [ 4√(17) + In( 4 + √( 17)) ]

Answer:
A. The triangles are similar because the ratios of the corresponding sides are the same
Step-by-step explanation:
Both ∆sloom similar in shape. Let's find out if they are actually similar.
∆TUV and ∆QRS are similar if the ratio of their corresponding sides are the same all through.
Thus:
TU = 70, QR = 25, UV = 84, RS = 30, TV = 42, QS = 15
If both ∆s are similar, then, TU/QR = UV/RS = TV/QS
TU/QR = 70/25 = 2.8
UV/RS = 84/30 = 2.8
TV/RS = 42/15 = 2.8.
Ratio of corresponding sides is the same, therefore, both triangles are similar.
Therefore, the following statement is true:
A. The triangles are similar because the ratios of the corresponding sides are the same

What is the equation of the line through the origin and (7,2)
Answer:
y=[tex]\frac{2}{7}[/tex]x
Step-by-step explanation:
First: find slope of line by using the formula [tex]\frac{y_2-y_1}{x_2-x_1}[/tex] with the two points (0,0) and (7,2)
slope(m) = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex] = [tex]\frac{2-0}{7-0}[/tex] = [tex]\frac{2}{7}[/tex]
Second: plug your data into the point slope formula [tex]y-y_1=m(x-x_1)[/tex]
y-0=[tex]\frac{2}{7}[/tex](x-0)
y-0=[tex]\frac{2}{7}[/tex]x
y=[tex]\frac{2}{7}[/tex]x

sam can make 18 burritos in 8 min write the ratio that compares the time to the number of burritos simplify if possible
Answer:
Ratio time to the number of burritos = 4:9
Step-by-step explanation:
Given:
Number of burritos make = 18
Total time taken = 8 min
Find:
Ratio time to the number of burritos
Computation:
Ratio time to the number of burritos = Total time taken / Number of burritos make
Ratio time to the number of burritos = 8 / 18
Ratio time to the number of burritos = 4 / 9
Ratio time to the number of burritos = 4:9

Clare earned a total of $12 for 2 hours of yard work. How many hours in all will it take Clare
to earn $18? Solve using unit rates.
Fast please asap thanks
Answer:
3 hours
Step-by-step explanation:
$12 = 2hours
Find how much Clare was paid for one hour
Total money earned ÷ number of hours = wage per hour
12 ÷ 2 = $6 per hour
set up equation
6x = 18
This equation says 6 dollars an hour × number of hours = $18
To solve for this equation, divide both sides by 6 (this isolates the variable)
6x ÷ 6 = 18 ÷ 6
1x = 3
x = 3
A number line going from negative 10 to positive 10. Point A is at 4, Point b is at 2, Point c is at negative 2, point d is at negative 4.
Which point represents the number 2?
The number 2 is at point
.
Answer: Point B represents the number 2 on the number line.
How?: Well, any whole number (without the minus/negative sign), is equal to a positive number. 2 is a whole number. So, therefore, it's Point B.

the mass of a block is 12g and the volume is 6 ml calculate the density of the block
a.) 0.5 g/ml
b.) 18 g/ml
c.)2 g/ml
d.)72g/ml
Answer:
c.)2 g/ml
Step-by-step explanation:
Given:
Mass of block = 12 g
Volume of block = 6 ml
Required:
Density of the block
SOLUTION:
Density is given as the mass of the block per unit volume.
Thus, density = mass/volume
Density of block = [tex] \frac{12 g}{6 ml} [/tex]
= 2 g/ml.
The answer is c. 2 g/ml.
A boat is 2000m from a cliff. If the angle of depression from the top of the cliff to the boat is 10 degrees, how tall is the cliff.
