Answer:
2x+30 = 90
Step-by-step explanation:
The two angles are complementary so they add to 90 degrees
2x+30 = 90
F(x) = 5*x - 12
f(2) = 5*2 - 12 .... replace every x with 2, then use PEMDAS to simplify
f(2) = 10 - 12
f(2) = -2
The final answer is -2, which is choice C

Answer:
b
Step-by-step explanation:
8x +4(x -1)
<em>Expand by multiplying 4 into each term inside the bracket:</em>
= 8x +4(x) +4(-1)
= 8x +4x -4
<em>Simplify</em>
= 12x -4
Thus, the answer is b.
