Mathematics
1 answer:
laiz [17]3 years ago

Answer:

<h2>BC = 25</h2>

Step-by-step explanation:

It's an isosceles triangle (congruent angles ∠C ≅ ∠B).

Therefore AC = AB.

We have the equation:

4x+1=2x+23        <em>subtract 1 from both sides</em>

4x=2x+22       <em>subtract 2x from both sides</em>

2x=22          <em>divide both sides by 2</em>

x=11

Substitute the value of <em>x</em> to the expression BC = 3x - 8:

BC = 3(11) - 8=33-8=25

The volume of a rectangular prism is:

V=xyz where x,y,z are the dimensions...

In this case:

V=5*(2 1/2)*(1 1/2)

which is equal to 

V=(12 1/2)*(1 1/2)

So the top one and the third one down are the correct volume.
