Answer:
If we multiply both the sides by 2, the inequality signs remains the same.
If we divide both sides by -2, the sign changes.
Step-by-step explanation:
The given inequality is
-8<2
If we multiply both the sides by 2, we get
-8 * 2 < 2*2
-16 < 4
The inequality signs remains the same.
On the other hand if we divide both sides by -2, we get -
-8/-2 < 2/-2
4 > -1
Here the sign changes.
First question: Answer is D
∵ Area of rectangle is L ⋅ W = 12 ⋅ 6 = 72 
∵ Area of the shaded region is 36 
∴ The area of the unshaded region =
the area of the whole rectangle - the shaded region =
72 - 36 = 36 
∴ The area of the unshaded region = 36 
Second question: Answer is A
∵ Area of triangle is
Bh =
⋅ x ⋅ 4 = 32
∵ Height (h) = 4 ft
∴ Base (B) =
⋅ 2 = 8 ⋅ 2 = 16
∴ Base (B) = 16 ft
Third question: Answer is D
6.009 = 6 + 0.009
Fourth question: Answer is B
104.0032 = One hundred four and thirty-two ten-thousandths
Fifth question: Answer is B
∵ Perimeter of rectangle = 2(W+L) =
2(80+120) = 2 ⋅ 80 + 2 ⋅ 120 = 160 + 240 = 400 
∴ He needs 400

To find the slope in the graph you need to find two perfect points on the line then count how many times you went up which is the y over how many times you go right which is the x its called the rise/run. To find the slope in the equation use the formula y2-y1/x2-x1.
