Answer:
the width is 46 and the length is 99
Step-by-step explanation:
perimeter = 290 yards
length =2w+7
width =w
perimeter = 2w + 2l =290
2w+ 2(2w+7) =290
2w+4w+14= 290
6w = 276
w= 46
4c - 2
Add up all the terms to find the perimeter.
2c + 2(c - 1)
2c + 2c - 2
Therefore, the perimeter is 4c - 2.
B
(x-8)^2=(x-8)(x-8)=x^2-8x-8x+64=x^2-16x+64
