SA = 2(LW +WH +LH)
= 2((4x +3)(x) +(x)(3x -1) +(4x +3)(3x -1))
= 2(4x^2 +3x +3x^2 -x +12x^2 +5x -3)
= 38x^2 +14x -6

-3x - 3/4 + 3/4 = 9 + 3/4
-3x = 9 3/4
I change 9 3/4 to improper fraction
-3x = 39/4
-3x / -3 = 39/4 / -3
X = 39/4 x -1/3 (change division to multiplication so that you can complete the problem)
X = -39/12
You can convert that if you want to -3 3/12
So x = -3 3/12
Simplify to x = -3 1/4

The mean of the numbers 11,-7,-14,10,-5 is found by adding all the numbers together, and then dividing by the number of numbers. In this case, the mean is -1.
Explanation:
To find the mean of the numbers 11,-7,-14,10,-5, you'll want to add all of these numbers together then divide by the amount of numbers there are. This is because the mean is the average value of a set of numbers.
First, add up all your numbers: 11 + -7 + -14 + 10 + -5, which totals to -5. There are 5 numbers in the set, so to find the mean, you then divide -5 by 5, which equals -1. So, the mean of the set of numbers 11, -7, -14, 10, -5 is -1.
