Answer:
Step-by-step explanation:
Given
Equation is
Mila uses the first step as multiplication to make the coefficient of x, 1
Mila maybe have multiplied the whole equation by 2 i.e.
1/2n+8=c one half of n plus 8 equals c
C. -10x+32
Explanation: Solve the problem
( -4(2x-8)-2x )
The missing factor is (a -1) I believe. If you foil (5a + 9)(a - 1) you would get 5a^2 + 4a - 9.
