Find and simplify the product of the following rational expression
alekssr [168]
I would say it’s b

You can cross cancel (x-3) out of both fractions
Then you have x+2/ x times 3/4
Multiply the numerators
3(x+2)
And the denominators
x • 4 = 4x
Leaving you with 3(x+2)/4x
You can simplify it further into 3x+ 6/ 4x which is option b, though it is technically simplified with the parentheses.

If a cube has a<br> volume of 8 cm<br> what is it's side<br> length?
lana [24]
Side length: 2 cm.

Volume of a cube:
V=a^3
(where V is volume, and a is side length)

If v=8, the formula would now be 8=a^3

Take the cube root of both sides

a=2.

Are these rates equivalent, 96 words typed for 3 minutes; 160 words typed for 5 minutes
monitta
<h2>Greetings</h2>

Answer:

Yes, they are.

Step-by-step explanation:

<h3>1st rate)</h3>

Lets simplify both rates to the rate typer per minute.

(m is minutes)

3m = 96

Divide both sides by 3:

\frac{3m}{3} = \frac{96}{3}

m = 32

So the rate is 32 words per minute.

<h3>2nd rate</h3>

5m = 160

Divide both sides by 5:

\frac{5m}{5} = \frac{160}{5}

m = 32

<h3>So because the rates per minute are the same, they are equivalent.</h3>
<h2>Hope this helps!</h2>
