Question

Suppose the area of a rectangular paper parachute used for disaster relief is 260 square feet. If one side of the parachute measures 2x + 4 and another side measures 8x + 2, what is the value of x?

Answer 1

Answer:

x= 2.6ft

Step-by-step explanation:

Step one:

given

A= 260ft^2

W= 2x + 4

B=8x + 2

Step two:

A=L*W

260=(2x+4)*(8x + 2)

open bracket

260=16x^24x+32x+8

16x^2+56x-252=0

Solving using quadratic formula

the roots are

x=-6.0

x= 2.6

Hence the value of x= 2.6ft
