Answer:

The volume for the triangular prism is 40.5 cubic inches.

Step-by-step explanation:

Given:

The base of a triangular prism has an area of 18 square inches .  

And the height is 4.5 inches.

Now, to get the triangular prism volume.

The base area = 18 square inches.

Height = 4.5 inches.

Now, to get the volume of prism we put formula:

Volume=\frac{1}{2} \times base\ area\times height\\\\Volume=\frac{1}{2} \times 18\times 4.5\\\\Volume=40.5\ cubic\ inches.

Therefore, the volume for the triangular prism is 40.5 cubic inches.

Answer:

x = 3

General Formulas and Concepts:

  • Left to Right

Equality Properties

Step-by-step explanation:

<u>Step 1: Define Equation</u>

17 - (3x + 5) = 3x - 6

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

  1. Distribute negative:                   17 - 3x - 5 = 3x - 6
  2. Add 3x on both sides:               17 - 5 = 6x - 6
  3. Combine like terms:                  12 = 6x - 6
  4. Isolate <em>x</em> term:                            18 = 6x
  5. Isolate <em>x</em>:                                     3 = x
  6. Rewrite:                                      x = 3

<u>Step 3: Check</u>

<em>Plug in x into the original equation to verify it's a solution.</em>

  1. Substitute in <em>x</em>:                    17 - (3(3) + 5) = 3(3) - 6
  2. Multiply:                               17 - (9 + 5) = 9 - 6
  3. Add:                                     17 - 14 = 9 - 6
  4. Subtract:                              3 = 3

Here we see that 3 does indeed equal 3.

∴ x = 3 is the solution to the equation.
