Answer:
-8a -8b + 8c
Step-by-step explanation:
-8(a + b - c)
-8 x a is -8a
-8 x b is -8b
-8 x -c is 8c
<u />
<u>-8a -8b + 8c</u>

Answer:
The answer is 10√2.
Step-by-step explanation:
The question doesn’t make much sense. Do you mean x=50-12? If so, x=38
This situation can be represented by
y = 33x + 223
y = 32x + 239
I still like substitution, so let’s plug in 33x + 223 into the second equation
33x + 223 = 32x + 239
Move the terms into appropriate sides
33x - 32x = 239 - 223
Combine like terms
x = 16
Then plug in x for any equation
y = 32(16) + 239
y = 751

We have that the total length of paper needed to cover all the tables is
From the question we are told that:
Number of tables 
Length of table
Extension 
Generally, the equation for the Total length tables is mathematically given by
Therefore with an extension of 0.25ft at both end we have the Total length of tablecloths to be
In conclusion
The total length of paper needed to cover all the tables is
