2d+4=10+2.5d Help Me

1 answer:

6 0

Subtract 2d from both sides

simplify 10 + 2.5d - 2d to 10 + 0.5d

subtract 10 from both sides

simplify 4 - 10 to -6

divide both sides by 0.5

simplify 6/0.5 to 12

switch the sides

Answer: d = -12.

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.
