self explanatory-
but you divide 1 by 7 you get 7
Answer:
$62.50 for 50 feet
Step-by-step explanation:
$7.50/(6 feet) = $1.25/foot
($1.25/foot)*(50 feet) = <u>$62.50 for 50 feet</u>
To get the common denominator you would multiply the first term by (x-4)/(x-4) and you multiply the second term by (x+4)/(x+4):
<span> (x-4) 4 </span> + <span> x (x+4)</span>
(x-4)(x+4). (x-4)(x+4)
The next step is to distribute the 4 (x-4) and the x (x+4)
so now you have
4x-16 + x^2 + 4x
(x - 4) (x + 4)
now combine like terms and put them in order exponents
<span>x^2 + 8x - 16
</span>(x-4)(x+4)
Since x^2 + 8x - 16 is not factorable you are done. That is your answer:
<span><u>x^2 + 8x - 16</u>
</span>(x-4)(x+4)
