Answer:
The answer to your question is x = 2
Explanation:
Data
Area = 192 in²
Polynomial 2x² + 48x + 88
Process
1.- Write an equation of the area
2x² + 48x + 88 = 192
2.- Factor
2x² + 48x + 88 - 192 = 0
2x² + 48x - 104 = 0
Divide by two
x² + 24x - 52 = 0
(x + 26)(x - 2) = 0
x₁ = - 26 x₂ = 2
The answer is x = 2, it could not be -26 because there are no negative lengths.
