We will use the FOIL method to solve this.
(7x-7)(x+1)
Multiply 7x by x. Then, multiply 7x by 1. Then, multiply -7 by x. Then, Multiply -7 by 1.

Now, we need to simplify by combining like terms.

If you look, -7x and 7x are gone. This is because they cancel each other out.
I hope this helped and maybe consider giving me brainliest :)
Use the side lengths! C and D have lengths of 3 and heights of 4.
Also use how far away they are from the axis.
Both C and D are 2 away from each axis on the end point.
This also goes with A.
However, B does not seem to be congruent in the sense of (coordinates)
It is the same length and height.
Answer:
X= -4
Step-by-step explanation:
^ you have to isolate the radical than raise each side to the power of its index which gets you
x= -4
Answer:
It's 8 the answer is 8
Step-by-step explanation:
The answer is -6 because the square root of 36 is 6, but then you have to add the negative in front of it.
