Answer:
To solve the equation, you have to to isolate the variable. So, first you subtract both sides by 7.
x +7 - 7 = -2 - 7
When you simplify further,
x = -9.
Hope this helps! :)

We must find the volume of a box with:
• square base with diagonal ,h = 6 cm,,
,
• height ,H = 15 cm,.
1) First we compute the length of the sides of the square base.
From the diagram above, we see that the diagonal of the box constitutes the hypotenuse of a triangle of sides a. Pitagoras Theorem states that the square of the hypotenuse is equal to the sum of the squares of the other sides, so we have:
Replacing the value h = 6 cm, and solving for a², we get:
2) The volume is given by the product of height (H) and the area of the base (a²):
Answer
The volume of the box is 270 cm³.
