Simplify<br> (7x - 7)(x + 1)

Nadusha1986 [10]

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.

$7x^{2} + 7x - 7x -7$

Now, we need to simplify by combining like terms.

$7x^{2} -7$

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 :)

1-) Emily and her friends went to the park. They saw 15 robins and 9 blue jays. How many birds did they see.? 24 birds.

I decided to do a addition problem because based on the answer it couldn't be multiplication, subtraction, or division. Therefore, my problem would look like 15+9=24 birds in total.
