Answer:
n = 9
Step-by-step explanation:
Step 1: Write equation
-4(9n + 9) = -12(4n - 6)
Step 2: Solve for <em>n</em>
<u>Distribute:</u> -36n - 36 = -48n + 72
<u>Add 48n to both sides:</u> 12n - 36 = 72
<u>Add 36 to both sides:</u> 12n = 108
<u>Divide both sides by 12:</u> n = 9
Step 3: Check
<em>Plug in n to verify if it's a solution.</em>
-4(9(9) + 9) = -12(4(9) - 6)
-4(81 + 9) = -12(36 - 6)
-4(90) = -12(30)
-360 = -360

Answer:
- 132
Step-by-step explanation:
This can be evaluated without a calculator.
Take each part of the calculation and evaluate, that is
- 6(3)(- 4) = - 6 × - 12 = 72
3(3)²(- 4) = 3 × 9 × - 4 = - 12 × 9 = - 108
2(3)(- 4)² = 6 × 16 = 96
Putting the 3 parts back together
72 - 108 - 96
= 72 - 204
= - 132
