Answer:

Step-by-step explanation:

Start by factoring out a 5:

We need to find two integers that have a product of 12, and a sum of -7:
(-3)(-4)=12
-3-4=-7
We can split -7x into -3x and -4x

Factor each half separately:
![5[x(x-3)-4(x-3)]](https://tex.z-dn.net/?f=5%5Bx%28x-3%29-4%28x-3%29%5D)
Since x and -4 are both being multiplied by x-3, we can combine them:

Answer:
x=9
Step-by-step explanation:
Multiply both sides by 2.
x+3= 12
Subtract both sides by 3.
x=12-3
x=9
I believe the answer is 10
22.50 divided by 9 to show how much for 1 hour. That is 2.5 so next 2.5 x 4 = 10
I don’t completely know if this is correct but I believe it is
