Answer:
x² + x - 12 = 0
Step-by-step explanation:
Given the solutions are x = - 4 and x = 3, then the factors are
(x + 4) and (x - 3) and the equation is the product of the factors, that is
(x + 4)(x - 3) = 0 ← expand factors using FOIL
x² + x - 12 = 0 ← in standard form
Answer: 125 squared ft
<em />
<em>Area of the big rectangle </em>⬜️<em>, 15ft x 10ft = 150 square ft</em>
<em>Area of the small square(which is spaced), 5ft x 5ft = 25 squared ft</em>
<em>Area of the give figure, 150squared ft- 25squared ft = 125 squared ft</em>
The perpendicular of that would be y=3x+12.
