X=Amount of games in each case.
He has 2 cases of videos games with the same number of games in each case:
2x+2x
He gives 4 away to his brother:
2x+2x-4
Now he has 10 games left:
2x+2x-4=10
4x-4+4=10+4
4x/4=14/4
X=3.5. round up to 4 because you can’t have .5 of a game.
Richordo had 4 video games in each case.
Following the setps we have that
![\begin{gathered} n\cdot n=64 \\ n^2=64 \\ n=\sqrt[]{64}=8 \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20n%5Ccdot%20n%3D64%20%5C%5C%20n%5E2%3D64%20%5C%5C%20n%3D%5Csqrt%5B%5D%7B64%7D%3D8%20%5Cend%7Bgathered%7D)
the lengths of the sides of the original square is 8 inches each one. Now we are going to find the lengths of the sides of the new square following the step 2
the lengths of the sides of new square is 12 inches each one.
-34.68 - (-49.62) = -34.68 + 49.62 = 14.94 degrees warmer at the north pole
