<h3>Answer:
49y^2 - 56</h3>
===============================
Work Shown:
7y^2 + 7(6y^2 - 8)
7y^2 + 7(6y^2) + 7(-8)
7y^2 + 42y^2 - 56
49y^2 - 56
The length would be 20 in.

Answer:
55/84
Step-by-step explanation:
1. Add (1/12) to (4/7)
To do this you will have to find a common denominator which would be 12*7 (84).
2. Convert the fractions to have a denominator of 84.
1/12 ---> 7/84
4/7 ---> 48/84
3. Add both fractions together to get "x"
55/84 = x
The three even integers are 80, 82, and 84.
The sum of the first (80) and the third (84) integers = 80 + 84 = 164, verifying our answer.
A simple way to figure this out is to divide 164 by 2, which gives you 82. From this answer, if we subtract 2 to get the first integer and add 2 to get the third integer while keeping 82 as the second integer, we end up with the correct sum of 164.
Hope this helps!
