Answer:
3(a + 5b + 7c) and 2x(2 + 5y + 11z)
Step-by-step explanation:
3a + 15b + 21c
3(a + 5b + 7c)
4x + 10xy + 22xz
2x(2 + 5y + 11z)
Answer:
B) 60
Step-by-step explanation:
<u>Given:</u>
- <A = 2x
- <B = 60
- <A and <B are supplementary angles (they add up to 180)
<u>Equation:</u>
<A + <B = 180
2x + 60 = 180
2x = 180 - 60
2x = 120
x = 60
