Answer:
- 9z^2
Step-by-step explanation:
Since the negative sign is outside of the parentheses it is not raised to the power of 2
- ( 3z) ^2
- ( 3z) * (3z)
I just edited the file you linked.
3x-2x-7
=x(plus symbol)7
x = -1.1
3(5x - 8) = -5(-x + 7)
15x - 24 = 5x - 35
15x - 5x = -35 + 24
10x = -11
x = -11/10
