Answer:
The solutions are x = -4 and x = 4.
Step-by-step explanation:
Solving a quadratic equation:
We have to find x for which
.
In this question:
![y = 16 - x^2](https://tex.z-dn.net/?f=y%20%3D%2016%20-%20x%5E2)
So
![16 - x^2 = 0](https://tex.z-dn.net/?f=16%20-%20x%5E2%20%3D%200)
![x^2 = 16](https://tex.z-dn.net/?f=x%5E2%20%3D%2016)
![x = \pm \sqrt{16}](https://tex.z-dn.net/?f=x%20%3D%20%5Cpm%20%5Csqrt%7B16%7D)
![x = \pm 4](https://tex.z-dn.net/?f=x%20%3D%20%5Cpm%204)
The solutions are x = -4 and x = 4.

Answer:
A = 140 in²
Step-by-step explanation:
The area (A) of the triangle is calculated as
A =
bh ( b is the base and h the perpendicular height )
here b = 20 and h = 14 , then
A =
× 20 × 14 = 10 × 14 = 140 in²
