Answer:

\displaystyle L=4x^{4}y^{8}z^{12}

Step-by-step explanation:

<u>The Volume of Rectangular Prism</u>

Given a rectangular prism of width W, height H, and length L, its volume is calculated as follows:

V = WHL

We are given the volume of a rectangular prism:

V=72x^8y^{14}z^{22}

It's also known the width is:

W=6x^3y

And height

H=3xy^5z^{10}

Substituting in the formula, we solve for L:

72x^8y^{14}z^{22}=(6x^3y)*(3xy^5z^{10})L

\displaystyle L=\frac{72x^8y^{14}z^{22}}{(6x^3y)*(3xy^5z^{10})}

Operating the denominator

\displaystyle L=\frac{78x^8y^{14}z^{22}}{18x^4y^6z^{10}}

Dividing:

\displaystyle L=4x^{8-4}y^{14-6}z^{22-10}

Simplifying:

\boxed{\displaystyle L=4x^{4}y^{8}z^{12}}

Why do teachers make math so hard
ikadub [295]

Answer:

Step-by-step explanation:

Math on it's own is not hard. It's the way teachers teach it. It also could be your brain, some peoples brain (like my own) aren't made for math where there is only one answer but for creative interprutive answers like philosophy and art. Some minds are good for sports. Find what your mind is good for and you never go wrong.

Given two independent events A and B, the probability of both event A and event B occurring is equal to the probability of A plu
Alona [7]

Answer:

Step-by-step explanation:

You would add probabilities if you want to find out if one event or another could happen. For example, if you roll a die, and you wanted to know the probability of rolling a 1 or a 6, then you would add the probabilities:

Probability of rolling a 1: 1/6

Probability of rolling a 6: 1/6

So the probability of rolling a 1 or a 6 is 1/6 + 1/6 = 2/6 = 1/3.
