Answer:
B
Step-by-step explanation:
x² + 8x + 7 = 0
x²+x+7x+7=0
x(x+1)+7(x+1)=0
(x+1)(x+7)=0
Either x=-1or x=-7.
Answer:
<h2>The missing value is 3, and the coordinates are (3,3).</h2>
Step-by-step explanation:
The complete question is

Complete the missing value in the solution to the equation. (3, ? )
By given, we know that
, because coordinates are written like
.
Then, we replace the given coordinate to find
.

Therefore, the missing value is 3, and the coordinates are (3,3).
i am not shure what the answer is to this?
Answer:
3/5=x/z
Step-by-step explanation:
7x=3y
7(3)=3(7)
21=21
5y=7z
5(7)=7z (plug in the seven from the first step)
35=7z
then divide both sides by 7
5=z
therefore, X/Z=3/5
