Answer:
65
Step-by-step explanation:
Exterior angle = Sum of 2 interior angles
x + 31 = x + x - 34
x + 31 = 2x - 34
x - 2x = - 34 - 31
- x = - 65
x = 65
Answer:
D: 6√30
Step-by-step explanation:
Simplify the following:
sqrt(20) sqrt(3) sqrt(18)
sqrt(18) = sqrt(2×3^2) = 3 sqrt(2):
sqrt(20) sqrt(3)×3 sqrt(2)
sqrt(20) = sqrt(2^2×5) = 2 sqrt(5):
2 sqrt(5) sqrt(3)×3 sqrt(2)
2×3 = 6:
6 sqrt(5) sqrt(3) sqrt(2)
sqrt(5) sqrt(3) sqrt(2) = sqrt(5×3×2):
6 sqrt(5×3×2)
5×3 = 15:
6 sqrt(15×2)
15×2 = 30:
Answer: 6 sqrt(30)
-3 because 4 times -3 = -12 -7=-19
Answer:
none
cz there's no no. that repeats itself
