Please help I’m struggling on this question.

Answer: \frac{2(y^2-4y+40)}{(y-8)(y+4)}

Step-by-step explanation:

To solve this problem, we want to make sure the denominators are the same on both fractions. Once they are equal, we can dd them together.

\frac{y+4}{y-8} +\frac{y-8}{y+4}                      [multiply first fraction by y+4 and second by y-8]

\frac{(y+4)(y+4)}{(y-8)(y+4)} +\frac{(y-8)(y-8)}{(y-8)(y+4)}   [distribute by FOIL]

\frac{y^2+8y+16}{(y-8)(y+4)} +\frac{y^2-16y+64}{(y-8)(y+4)}   [add numerator]

\frac{y^2+8y+16+y^2-16y+64}{(y-8)(y+4)}         [combine like terms]

\frac{2y^2-8y+80}{(y-8)(y+4)}                       [factor out 2 from numerator]

\frac{2(y^2-4y+40)}{(y-8)(y+4)}                  

Now we know that \frac{2(y^2-4y+40)}{(y-8)(y+4)} is the factored form after adding.

Can someone help me on this ? its Algebra 1 on exponents
Svetradugi [14.3K]
The volume of a rectangular prism is its length times width times height, or algebraically, V=lwh. You may be used to computing volume with numbers, but remember, a variable is a stand-in for a number. So you can solve this in the same way. Substitute l=x, w= \frac{x}{2},h= \frac{x}{3} into the formula for volume. You get (x)( \frac{x}{2})( \frac{x}{3} ), and you multiply these factors together. As you would with ordinary fractions, multiply the numerators and denominators across. You get \frac{(x)(x)(x)}{(1)(2)(3)} =  \frac{x^3}{6}. It seems that the book wants you to simplify by bringing the 6 up to the denominator. Recall the rule x^{-n}= \frac{1}{x^n}, if n is non-negative. The opposite applies so that \frac{1}{6} = 6^{-1}. For your final answer, you write 6^{-1}x^3. This corresponds to answer choice B.
