Answer:
see below
Step-by-step explanation:
-7(x+2)+4x=6(2x-4)
Distribute
-7x -14 +4x = 12x -24
Combine like terms
-3x-14 = 12x-24
Add 3x to each side
-3x-14+3x = 12x-24+3x
-14 = 15x-24
Add 24 to each side
-14+24 = 15x -24+24
10 = 15x
Divide each side by 15
10/15 =15x/15
2/3 =x
Answer:
-18v + 9w +15
Step-by-step explanation:
-3(6v-3w-5)
You can use a table or multiply each term
-3(6v) + -3(-3w) + -3(-5)
= -18v + (9w) + (15)
= -18v + 9w + 15
Answer:
9 inches
Step-by-step explanation:
(x + 2)² = 121
√(x + 2)² = √121
x + 2 = 11
x + 2 - 2 = 11 - 2
x = 9
Answer: About 90 something, I believe I'm sorry I'm a bit rusty in these math problems.
