Step-by-step explanation:
cross multiply all equations seperately
1,n=63
2.n=24
3.n=19
4.n=20
The answer to your problem is C the third picture
I think it’s p=36 because you have to do the opposite on both sides..
So..
q=-12
P/-12=-3
+12 *12
P=36
Answer:
see below
Step-by-step explanation:
1st: x
2nd: 5x + 8
x(5x + 8) = 36
5x² + 8x = 36
5x² + 8x - 36 = 0
(x - 2)(5x + 18) = 0
(x - 2) = 0
x - 2 = 0
x = 2
1st: x = 2
2nd: 5x + 8 = 5(2) + 8 = 18
(5x + 18) = 0
5x + 18 = 0
5x = -18
x = -3.6
1st: x = -3.6
2nd: 5x + 8 = 5(-3.6) + 8 = -18 + 8 = -10
