Answer:#1 C.30 #2 40


Step-by-step explanation:

3x+15=7x-5

3x+15+5=7x-5+5

3x+20=7x

3x-3x+20=7x-3x

20=4x

20/4=4/4x

5=x so if it is an equilateral all sides are equal so 3(5)+15=30 so the answer should be 30

So the triangle in #2 is an isoceles so two of the angles are equal so the equation is 2(2x-24)+3x+4=180

4x-48+3x+4=180

7x-44=180

7x=224

x=32

2(32)-24

64-24=40

The base of a triangular prism has an area of 18 square inches . If the height of the prism is 4.5 inches then what is the volum
Nady [450]

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.
