Answer:

  -15, 3

Step-by-step explanation:

3|x+6| -7 = 20

3|x +6| = 27 . . . . add 7

|x +6| = 9 . . . . . . divide by 3

This resolves to two equations:

  x + 6 = 9

  x = 3 . . . . . subtract 6

and

  x + 6 = -9

  x = -15 . . . . subtract 6

Simplify the expression by combining like
viva [34]

Answer:

Below

Step-by-step explanation:

First we combine your first set of terms,

7b^2 + 2b^2 = 9b^2

There's a subtraction hidden in there!

9b^2 - 3b^2 = 6b^2

Next we do the same thing for the second term,

3b + 7b = 10b

but there's a subtraction in the expression!

10b - b = 9b

Then we finish with our third term

6 + 5 = 11

Answer:

6b^2 + 9b + 11
