Alecsey [184]
The volume of a triangular prism is equal to :
area of the base x height

the area of the base :
10 \times 4 \div 2 = 40 \div 2 = 20

so the volume is
20 \times 8 = 160

the answer is 160m^3

How do I solve 6(5 - 2x) + 12 = -66?
ladessa [460]

Answer:

x = 9

Step-by-step explanation:

Step 1: Write equation

6(5 - 2x) + 12 = -66

Step 2: Solve for <em>x</em>

  1. Distribute 6: 30 - 12x + 12 = -66
  2. Combine like terms: 42 - 12x = -66
  3. Subtract 42 on both sides: -12x = -108
  4. Divide both sides by -12: x = 9

Step 3: Check

<em>Plug in x to verify it's a solution.</em>

6(5 - 2(9)) + 12 = -66

6(5 - 18) + 12 = -66

6(-13) + 12 = -66

-78 + 12 = -66

-66 = -66
