Answer 1

Answer:

Answer 2

$\bold{AnsweR:}$

Step-by-step explanation:

W = 3ft

L = 3ft

Step-by-step explanation:

L = 2x -3

W = x

(2x - 3) (x) = 9

2x^2 - 3x = 9

Transpose

2x^2 - 3x - 9

Apply Quadratic Trinomials

ac = factors of -18 wherein 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 .
