It might be 2.5 but I could be wrong
Answer:
See explanation
Step-by-step explanation:
If a quadratic trinomial has a leading coefficient of 1 and a positive constant, then it is very easy to factor.
You just have to look for two factors of the constant term that add up to the coefficient of x( the middle term).
Then you write as factors.
For instance;

To factors of 6 that add up to 5 are 2 and 3.
Therefore the factorization is:

Answer:
B
Step-by-step explanation:
-2 is greater than -3
Answer:
We have 16 ounces of 3% H2O2
How many ounces of 30% H2O2 do we add to make a 10% H2O2 solution?
let x = amount of ounces of 30% H2O2 to add
.03 * 16 + .30x = .10 * (16 + x)
.48 + .30x = 1.6 + .1x
.2x = 1.12
x = 5.6 ounces

Step-by-step explanation:
25 and -12 because when you subtract 12 from 25 you will get 13 and when you multiply 25 by -12 you will get -300
