Answer:
Step-by-step explanation:
![x\le -4\\ \\ g(-4)=\sqrt[3]{-4+5}\\ \\ g(-4)=\sqrt[3]{1}=1](https://tex.z-dn.net/?f=x%5Cle%20-4%5C%5C%20%5C%5C%20g%28-4%29%3D%5Csqrt%5B3%5D%7B-4%2B5%7D%5C%5C%20%5C%5C%20g%28-4%29%3D%5Csqrt%5B3%5D%7B1%7D%3D1)
Question a:
f(6) = (6)² + 2(6) + 8
f(6) = 36 + 12 + 8
f(6) = 56
Question b:
f(x+4) = (x+4)² + 2(x+4) + 8
f(x+4) = x² + 8x + 16 + 2x + 8 + 8
f(x+4) = x² + 10x + 32
Question c:
f(-x) = (-x)² + 2(-x) + 8
f(-x) = x - 2x + 8
For this case we must simplify the following expression:

We must add similar terms taking into account that:
- Equal signs are added and the same sign is placed.
- Different signs are subtracted and the major sign is placed.

Thus, the simplified expression is:

Answer:

Answer:
x = 22°
the angles are: 63° and 117°
Step-by-step explanation:
a linear pair of angles total together to be 180°
so:
3x - 3 + 5x + 7 = 180
combune like terms:
8x = 176
divide both sides of the equation by 8:
x = 22°
the angles are: 63° and 117°
