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)
Answer:
7m
Step-by-step explanation:
v=πr^2h
769.3=3.14*r^2*5
769.3=15.7r^2
769.3/15.7=15.7r^2/15.7
49=r^2
√49=√r^2
√49=r
r=7m
Answer: 700 + 60 + 4
Step-by-step explanation:
So starting with the first inequality, m - 2 < -8, add 2 on both sides of the equation and <u>your first half is m < -6.</u>
Next, with m/8 > 1, multiply both sides by 8 and <u>your second half is m > 8</u>
Putting it together, <u>your answer is m < -6 OR m > 8.</u>
ling's equation is wrong because ling is dividing and then multiplying by the same thing which will just equal 0.
Correct equation:
9/(3/8) to find the time it takes to walk 1/8 then multiply the dividend by 8/8
