ANSWER :
A = 0
STEP BY STEP EXPLANATION
A = lenght × width
length = x+5
width = x-5
SUBSTITUTE
A = lenght × width
A= (x+5)(x-5)
A= x²-5x +5x -25
COMBINE THE LIKE TERMS (which is -5x and 5x)
A= x²-25
TRANSPOSE THE (-25)
25 = x²
USE SQUARE ROOT BOTH SIDE
[tex] \sqrt{25 } = {x}^{2} [/tex]
5 = x
SUBSTITUTE IT
A= length × width
A = (5+5)(5-5)
A = (10)(0)
A = 0
