Answer:

Solve for X ( The question I did was an example )

Step-by-step explanation:

To solve and equation like 2x+9=30 you will have to isolate the number with a variable. You need to subtract 9 on both sides for that to happen.

2x=21

Now the next step is to divide. You have to divide to get the answer.

x=21/2

x= 10.5

The two right triangular prisms are similar solids.

Zanzabum

Answer:

<h2>The volume of the larger prims is eight times greater than the smaller prism.</h2>

Step-by-step explanation:

If the scale factor of the larger prims to the smaller prism is 3, that means each side is triple.

We know the a triangular prims has a volume defined by

$V_{small} =\frac{b \times h_{1} }{2} \times h_{2}$

If we take that formula as the smaller prism, then the larer prism has a volum of

$V_{large} =\frac{2b \times 2h_{1} }{2} \times 2h_{2}=8(\frac{b \times h_{1} \times h_{2} }{2} )$

If we compare, we can deduct that

$V_{large}=8V_{small}$

In words, the volume of the larger prims is eight times greater than the smaller prism.
