FOIL method : F = First , O = Outer , I = Inner, L = Last
(6x-6)(x+6)
First: 6x * x = 6x^2
Outer: 6x * 6 = 36x
Inner: -6 * x = -6x
Last: -6 *6 = -36
Put these in order and we get : 6x^2 + 36x -6x -36
Answer:
no solution
Step-by-step explanation:
30n-18+2n-14-64=30n-18+2n-14
32n-96=32n-32
-96=-32<-----false statement, therfore it is no solution

Answer:
7
Step-by-step explanation:
7(x - 3) = 28 Given
7x - 21 = 28 Distributive property
7x - 21 + 21 = 28 + 21 Addition property of equality
7x = 49 Division Property of equality
7x/7=49/7
x = 7
