mart [117]

Answer:

y = -9 or y = -4

Step-by-step explanation:

y^2 + 13y = -36

y^2 + 13y + 36 = 0

(y + 9)(y + 4)

y + 9 = 0

y = -9

y + 4 = 0

y = -4

Best of Luck!

The volume of a rectangular prism is 6x3 + 25x2 + 21x − 10. The length of the prism is 2x + 5. The width of the prism is 3x − 1.
aev [14]

Expression for the height of the prism is x + 2

<em><u>Solution:</u></em>

Given that,

Volume\ of\ a\ rectangular\ prism = 6x^3+25x^2 + 21x - 10

Length\ of\ prism = 2x + 5

Width\ of\ prism = 3x-1

To find: height of prism

<em><u>The volume of rectangular prism is given by formula:</u></em>

Volume = length \times width \times height

<em><u>Solving for height we get,</u></em>

height = \frac{volume}{length \times width}

<em><u>Substituting the values we get,</u></em>

height = \frac{6x^3+25x^2+21x-10}{(2x+5)(3x-1)}

<em><u>Factor the numerator</u></em>

height = \frac{(x+2)(3x-1)(2x+5)}{(2x+5)(3x-1)}

Cancel the common factors,

height = x + 2

Thus expression for the height of the prism is x + 2
