4 0

7x^2 - 7 = 0
7(x^2 - 1) = 0
7(x + 1)(x - 1) = 0
x = 1; x = -1

3 0

(1,0) (-1,0)
or if you prefer this format: x= 1,-1

Answer:

Second option, h=( $x^{2} + 4x$ ) ft

Step-by-step explanation:

Area = Base x Height

Height = Area ÷ Base

= $\frac{24x^{2} +96x}{24}$

= $\frac{24x^{2} }{24} +\frac{96x}{24}$ (split fraction for easier simplification)

= $x^{2} +4x$
