X^2 + 8x + 7= 0
(X+7)(X+1)
X=-1,-7
Answer:
yes
Step-by-step explanation:
It states your "X" will be zero when solving for "Y".
So when solving for "Y" your equation would be;
0+y=4
Then you solve. Y=4
Then you do the same with the "X":
X+0=4. Then you solve. X=4
It would end up being (4(x),4(y) )
Then do the same for the next problem.
8x4=32
32+40=72
72/2=36
36+6=42
The number is 42
