0
Step-by-step explanation:
2 + 2 = 4 and then 4 - 4 = 0
It is

The equation for area of a trapezoid is

Substituting our values in

We can then simplify the expression

Answer:
(-3)^2
Step-by-step explanation:
You add 7 on both sides, giving you x^2 - 6x = 7
Then, take half of b, and square it. Giving you x^2 - 6x +(-3)^2 = 7
The answer will be (-3)^2 for this question, but this is not the full solution.
Hope this helped. Good luck on the rest!
