Answer:
m<U=60°
Step-by-step explanation:

Answer:
C and D
Step-by-step explanation:
Let's add this all together.
9x + 5y + x - 3y
Combine like terms 5y + -3y and 9x + x
10x + 2y
So we know D is at least correct.
What else? C is also correct, because we can expand it outward.
10x + 5y - 3y = 10x + 2y
A and B are not correct! We can't multiply the ys or the xs.
Answer: (b) -5x + 5
<u>Step-by-step explanation:</u>
f(x) = 5x g(x) = -x + 1
f(g(x)): g(x) = -x + 1 f(-x + 1) = 5(-x + 1)
= -5x + 5
Would you go and answer my question? I am stuck on trying to find the fourth term of (a-b^2)^5
