Question

A rectangle has a perimeter of 8x3 + 7x2 - 10x + 3 and a length of x. Find the width of the rectangle

Answer 1

Answer:

If the length is x and the length is also 19 inches, then x=19 inches. The formula for perimeter is 2l+2w.

Substituting our given info into this equation...

2(19)+2w=6(6859)+9(361)-10(19)+7

2w+38=41154+3249-190+7

2w=44182

w=22091 inches.

Hope that helps!
