Working and answer in the photo above. Hope this helps
Answer:
D. 9 meters
Step-by-step explanation:
AB = CD, so 9x-27=2x+1.
If you get like terms on the same side you get 7x=28
If you simplify by dividing everything by 7, you get x=4
If you plug 4 in as x into the expression 2x+1, you get 9.
You are looking for the GCF or greatest common factor of 15 and 20 a way to do the is the upside down cake method.
Answer:

Step-by-step explanation:
Well we can simplify the numerator, by multiplying the 4 by the 6 and the m^3 and m^4 (add the exponents, explained in one of my previous answers I think)
This gives us the fraction: 
We can now divide the m^7 by m^2 by subtracting the exponents, and the reason why this works, is you're simply cancelling out the m's, If we express this in expanded form we have the following fraction: 
Since there is two m's in the denominator and there is also two (more than two) m's in the numerator, we can cancel those two m's out, and we get the fraction:
which can be simplified in exponent form as:
, now all we have to do is divide the 24 by the 3, to get 8
This gives us the answer:
