Answer:
x < –4 or x ≥ 3
Step-by-step explanation:
-20x-16
= -4(5x + 4)
I think 4 ×-5 = -20x
4×-4 = -16x
Answer:9
Step-by-step explanation:3x3= 9
(X3x3x3)
=9p
(3x²+4x-1) + (-2x²-3x+2)
3x²+4x-1 -2x²-3x+2
3x²-2x²+4x-3x-1+2
x²+x+1
86
This is because the angles should add up to 180. So 32 + 64 is 96. Then you subtract 96 from 180 to get 86.
