P = 2L + 2W
P = 2(2x) + 2(4x + 3)
P = 4x + 8x + 6
P = 12x + 6
The correct response would be D. 12x + 6.
The answer would be y=(x+4)^2-37
Answer:
u need 78 feet of the three foot wide fencing
22: 4x+8
23: 3x+21
24: 10x+35
27:39
28:48
29:36
30: 2(x+4)
32: 7(6x+7)
So originally, let's say the width of Frank's land was

feet.
The area of his land was therefore

, or

, as his land was square.
The width of his land then increased by 3 feet, and the height decreased by 3 feet.
So the new area of Frank's land is:

So the new land is now
9 square feet smaller, so it is not a fair deal for Frank.
Hope this helps :)
