(x-5)(x+7).
explanation:
(x-5)(x+7)=0
<=> x-5=0 or x+7=p
<=> x=5 or x=-7
18.5 - 6 = 12.5 gallons empty
12.5 / 18.5 = 0.676
0.676 x 100 = 67.6%
Answer: 67.6%
X/3 = 8/12
12 * x = 8 * 3
12x = 24
x = 2
8/12 = 4/y
8y = 48
y = 6
15^5 is 759,375

Answer:

Step-by-step explanation:
Given: 
Solution:
A differential equation is said to be separable if it can be written separately as functions of two variables.
Given equation is separable.
We can write this equation as follows:

On integrating both sides, we get

Formulae Used:

So, we get solution as 
Applying condition: x(0) = 1, we get 
Therefore,
