Answer: 82
Step-by-step explanation:
(N + 1 )^ 2 for N = -9
(-9 +1))^ 2

(-9 +1))^ 2 - Every number raised to power 2 positive your result will be positive
Step-by-step explanation:
180° = 2x + 70 + 4x + 10
180° = 2x + 4x + 70 + 10
180° = 6x+ 80
180 - 80 = 6x
100 = 6x
6x = 100
x = 16.66
x ≈ 17°
Answer:
b will be the right answer
I am sure
70-q-q-2q= 80
combine like terms first
so you get 70-4q= 80
subtract 70 on both sides and you get -4q= 10
divide -4 on both sides and you get q= 10/-4 or -2.5
