Answer:
First find the 30% of 5-liter cleaning solution.
3/10*5L=1.5L
We know 50% of 3L is 1.5.
If we add, the two bleach percentages, we get 3L of bleach.
When we add the two containers of cleaning solution, we get 8L.
The percentage of bleach in the mixture will be the ratio 3/8 expressed as a %.
3/8*100=37.5% of the cleaning solution will be bleach.
Answer: 37.5%

Answer:
C
Step-by-step explanation:
In this technique, if we have to factorise an expression like ax2+bx+c, we need to think of 2 numbers such that:
N1⋅N2=a⋅c=1⋅−12=−12
AND
N1+N2=b=−1
After trying out a few numbers we get N1=3 and N2=−4
3⋅−4=−12, and 3+(−4)=−1
x2−x−12=x2−4x+3x−12
x(x−4)+3(x−4)=0
(x+3)(x−4)=0
Now we equate the factors to zero.
x+3=0,x=−3
x−4=0,x=4
