Factor completely 18x2 − 21x −15. 3(2x 1)(3x − 5) 3(2x − 5)(3x 1) 3(2x − 1)(3x 5) 3(6x 1)(x − 5).

The factor of the $18x^{2} -21x-15$ will be 3(3x-5)(2x+1).

<h3>What will be the factor of $18x^{2} -21x-15$ ?</h3>

Given quadratic equation is $18x^{2} -21x-15$

By taking 3 common from whole of the equation it becomes.

$3(6x^{2} -7x-5)$

now by factorization equation will be.

$3(6x^{2} -10x+3x-5)$

3[(2x(3x-5)+1(3x-5)]

Taking (3x-5) common from whole equation it will become

3(3x-5)(2x+1).

Hence the factor of the $18x^{2} -21x-15$ will be 3(3x-5)(2x+1).

To know more about factorization follow.

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

$L=30\ in$

The area of a equilateral triangle is equal to

$B=\frac{1}{2}(10)^{2} sin(60\°)$

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

substitute

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