Answer:
Step-by-step explanation:
m∠3 = 18°
m∠1 = 90° - 18° = 72°
m∠2 = 180° - 2(72°) = 36°
m∠4 = 2(72°) = 144°

Answer:
Step-by-step explanation:
6x2 + 5x - 4
6x2 + 8x - 3x - 4
2x(3x + 4) - 1(3x + 4)
(2x - 1) (3x + 4)
These are the factors
Answer: Choice A) Distributive property
We're multiplying the outer -3 with the inner x to get -3x
Also, multiply the outer -3 with the inner +4 to get -12
So that's why -3(x+4) = -3x-12
