Since neither of the bracketed expressions is preceded by a minus sign, and neither one has a multiplier outside of it, all of the parentheses can simply be removed.

<span>(3x - 5) + (3x + 6)

3x - 5 + 3x + 6

Combine the 'x'-terms:  3x + 3x = 6x
Combine the numbers:  -5 + 6 = 1

The expression is equivalent to . . . . . <u>6x + 1</u>

15+(q/6)=-21

Subtract 15 from both sides
q/6= -36

Multiply both sides by 6.
q= -216

WARRIOR [948]

Answer: B

Step-by-step explanation:

Use the <u>Triangle Theorem.</u>

Now, we have to find every number involved squared.

2² = 4

3.6² = 12.96

Add the given components.

12.96 + 4 = 16.96

Our final answer is 16.96

Best of Luck!
