Answer:
Step-by-step explanation:
A
It is 146 because it is equal to the other large angle.
if 1 inch is added, you would add 2 inches to to each side of rectangle.
You would have: W+2, and, L+2,
Now let W+2 = x and, L+2 = y
Total area = x*y=M
If 1 inch is added again, like above you add 2 inches to both sides, you would then have:
(x+2)(y+2)=M+52;
xy+2x+2y+4=M+52;
xy=M
2x+2y=48
x+y=48/2=24
Now solve :
W+2+ L+2=24
W+L=20
The perimeter is 2(W+L)=20*2 = 40 inches.
The answer is A. -8
(step by step)
Do multiplication first. 7 * -8 = -56
Now subtraction. -56 - (-8) = -48

Answer:
y = -2.5x
Step-by-step explanation:
The constant of variation = y/ x = 5/-2 = -2.5
Also -7.5 / 3 = -2.5
-10 /4 = -2.5 and so on
