Answers:
1. a) 4.1x + 29
2. b) 1/5(m – 100)
3. c) nine over five y + 9 (9/5y + 9)
Explanations:
1. The formula for perimeter of a triangle is P = side a + side b + side c, so with these values it is:
2.3x + 14 + 2x – .2x + 15
Combine like terms:
4.1x + 29
2. Test the options to see which ones work out to the answer. You know that 1/5 of 100 = 20, so you need one with a 100 and a 1/5 in it. The only possible answer is:
1/5(m – 100)
3. Distribute the 3/5:
3/5 • 3y + 3/5 • 15 = 9/5y + 45/5 = 9/5y + 15
2 thirds = 2 x 3 = 6
1 half = 1 x 2 = 2
6+2 = 8
the answer is 8
Answer: c) 
Step-by-step explanation:

Let's rearrange from the 4th power to 1.

Combine like terms (check if they have the same variable raised to the same power.
