If all the cheese slices have same mass, say m grams
and mass of 3 cheese slices is 27
so,
m+m+m=27
3m=27
or m=27/3
m=9
thus
mass of one cheese slice is 9 grams
If you mean (3n-2m)^2 then the answer is
9n^2-12mn+4m^2
So B
<u><em>Answer: 6.3 *The answer must be have a decimal point.*</em></u>
Explanation:
First, subtract by the numbers. Subtract it's going to be find the difference between the numbers.

You can also add by the numbers.


Hope this helps!
Thank you!
Have a great day!
C=p+R x p
C=30.99 + .05 x 30.99
Order of operations states do the multiplication first
C=30.99 + 1.55
C=32.54
5n =70
5 x 14 = 70
hope this helped :)
