Question

the length of the rectangle is 3 less than twice the width . if the area is 9 square ft, the length and width of the rectangle


​

Answer 1

Answer:

W = 3ft

L = 3ft

Step-by-step explanation:

L = 2× -3

W = x

(2x -3) (×) = 9

2x^2 -3x = 8

Transpose

2x^2 -3x -9

Apply quadratic trinomials

ac = factors of -18 where in the sum of it is -3

-6 + 3

Rewrite

(2x^2 - 6x) + (3x-9)

Factor

2x(x - 3) + 3( x - 3)

Put ( x - 3 )

x - 3 = 0

Transpose

x = 3

Apply :

L = 2(3) - 3 = 3

w = 3
