Answer:
A
Step-by-step explanation:
substitute the values from the replacement set into the right side of the equation to find which values of x make the equation true.
x = - 32
+ 5 = - 8 + 5 = - 3 ← True
x = 8
+ 5 = 1 + 5 = 6 ≠ - 3 ← False
x = 32
+ 5 = 8 + 5 = 13 ≠ - 3 ← False
the solution is therefore x = - 32

Answer:
<em>342 square meters</em>
Step-by-step explanation:
Consider the length of j;
Applying the volume of a rectangular prism formula length * width * height = volume, we noted that 9, 9, and j corresponded to the length, width, and height of the rectangular prism and made it equivalent to the volume. Doing so, we solved for j. Now let us solve for the surface area;
Opposite faces are equal in terms of their area, so by finding the area of 3 faces, we multiply their area each by 2 to result in the total surface area!
