Find the value of x.
Area of rectangle = 36
▅ х
x + 5
The value of x is 4, which is determined by the quadratic equation.
What is the area of the rectangle?The area of a rectangle is defined as the product of the length and width.
The rectangle of a rectangle = L × W
Where W is the width of the rectangle and L is the length of the rectangle
We have been given that area of the rectangle = 36
Area of rectangle = width of the rectangle × length of the rectangle
Here the width of the rectangle = x
And length of the rectangle = x + 5
The rectangle of a rectangle = x × (x + 5)
36 = x² + 5x
x² + 5x - 36 = 0
x² + 9x - 4x - 36 = 0
(x + 9)(x - 4) = 0
x = -9 and x = 4
Take the value of x = 4 and the negative value is neglected because the dimension can't be negative.
Therefore, the value of x is 4.

if x+y=2, calculate:
P=4x (x-3)+4y(y-3)+8xy
Answer:
Step-by-step explanation:
P = 4x(x - 3) + 4y(y - 3) + 8xy
= 4x² - 12x + 4y² - 12y + 8xy
= (4x² + 8xy + 4y²) - (12x + 12y)
= 4(x² + 2xy + y²) - 12(x + y)
= 4(x + y)² - 12(x + y)
x+y =2 ⇒ P = 4.2² - 12.2 = 16 - 24 = -8

Gina Needs To Pack 130 Pens, 50 Pencils And 20 Erasers Into Identical Gift Bags So That Each Item Is Equally Distributed Among The Gift Bags. (I) Find The Largest Number Of Gift Bags That Can Be Packed. (Ii) Find The Number Of Each Item In A Gift Bag.
Answer:
Step-by-step explanation:
I think the best way is to split up the erasers before you do anything. That would mean there were 20 gift bags in all
If you did that, then each gift bag would contain 2 pencils with 10 left over.
Further 130 pens would divide up into 6 pens in each gift bag with 10 pens left over.

Suppose Karen reads 50 pages per day during the week, but then reads 1.5 times as many pages on Saturday and Sunday. How many pages total will Karen read on Saturday and Sunday?
Answer:
150 total pages read over the weekend, 75 for Saturday and 75 for Sunday.
Step-by-step explanation:
50×1.5=75
75+75=150
Answer:
Step-by-step explanation:
50 pages, 1.5 times as many
multiply:
50 x 1.5 = 75
If by "1.5 times as many on satuday and sunday" is including both days and not separately it will be 75 pages on saturday and sunday together..
If it says that she read 1.5 times as many on Saturday and 1.5 times as many on sunday, It will be 75 on saturday and 75 on sunday which is 150 pages.

What is the value of d that makes lines e and f parallel?
D=
10
13
85
115
Answer:
d = 13
Step-by-step explanation:
For the lines to be parallel, then
5(2d - 3) and (6d + 11 + 2d) will be corresponding angles and congruent, thus
5(2d - 3) = 6d + 11 + 2d ← distribute left side
10d - 15 = 8d + 11 ( subtract 8d from both sides )
2d - 15 = 11 ( add 15 to both sides )
2d = 26 ( divide both sides by 2 )
d = 13
The value of d that makes lines e and f parallel is 13units.
It is required to find the value of d.
What is line?A line is a straight one-dimensional figure having no thickness and extending infinitely in both directions. A line is made of a set of points which is extended in opposite directions infinitely. It is determined by two points in a two-dimensional plane. The two points which lie on the same line are said to be collinear points.
Given:
For the lines to be parallel, then
5(2d - 3) and (6d + 11 + 2d) will be corresponding angles and congruent.
According to given question we have,
5(2d - 3) = 6d + 11 + 2d
Distribute left side we get,
10d - 15 = 8d + 11
subtract 8d from both sides we get,
2d - 15 = 11
Add 15 to both sides we get,
2d = 26
Divide both sides by 2 we get,
d = 13units.
Therefore, the value of d that makes lines e and f parallel is 13units.

Answer: C
Step-by-step explanation:
The pair of angles created on the inner side of the parallel lines intersected by a transversal but on opposing sides of the transversal is known as an alternative interior angle. The correct option is C.
What are Alternate Interior angles?When two parallel lines are intersected by a transversal, the pair of angles created on the inner side of the parallel lines but on opposing sides of the transversal is known as an alternative interior angle. These angles are always equal in measure.
The best statements BEST that proves ∠XWY ≌ ∠ZYW is that If two parallel lines are cut by a transversal, then alternate interior angles are congruent.

Surveyors wished to know the distance across a lake between A and B. They measured the distance from B to C as 100 m and the angle from C to A to be 55°. Knowing that the angle between CB and BA was 90°, they used trig to solve for the distance. Show how it was done
Answer:
AB ≈ 70mStep-by-step explanation:
Check the attachment for the diagram.
You can see from the diagram that it is a right angled triangle with opposite side AB and adjacent side BC. Using SOH, CAH, TOA trig identity to get the length of AB. According to TOA;
tan 35° = opposite/adjacent
tan 35° = AB/BC
tan 35° = AB/100
AB = 100tan35°
AB = 100 * 0.7002
AB = 70.02m
Hence the distance across a lake between A and B is approximately 70m
