Answer:

The first answer which says 9x^{4} \sqrt{5}

Step-by-step explanation:

In this question, we just simplify the equation in the following way...

2x^{2} \sqrt{5x^{4} } +7\sqrt{5x^{8} } = 2x^{2} \sqrt{5} x^{2}  + 7\sqrt{5} x^{4} = 2\sqrt{5} x^{4} + 7\sqrt{5} x^{4} = 9\sqrt{5} x^{4} = 9x^{4} \sqrt{5}

Therefore the first answer it the right one.

6. A prism has bases that are equilateral triangles with sides lengths of 10 inches and a length of 30 inches.
eimsori [14]

Answer:

The volume of the prism is 1,299\ in^{3}

Step-by-step explanation:

we know that

The volume of the prism is equal to

V=BL

where

B is the area of the triangular base

L is the length of the prism

we have

L=30\ in

<em>Find the area of the base B</em>

The area of a equilateral triangle is equal to

B=\frac{1}{2}(10)^{2} sin(60\°)

B=25\sqrt{3}\ in^{2}

substitute

V=(25\sqrt{3})(30)=1,299\ in^{3}
