Answer:
C
Step-by-step explanation:
m = 5x - 2
(5x - 2)² + 35x - 14 = -12
(5x - 2)² + 7(5x - 2) = -12
Replace (5x - 2) by m in the equation above
m² + 7m = -12
m² + 7m + 12 = 0

Answer:
8x + 2y
Step-by-step explanation:
You need to use distributive property.
5(x + y)
5 · x = 5x
5 · y = 5y
3(x - y)
3 · x = 3x
3 · -y = -3y (don't forget the sign)
So,
5x + 5y + 3x - 3y
Arrange them,
5x + 3x + 5y - 3y
Simplify,
5x + 3x = 8x
5y - 3y = 2y
So,
8x + 2y
