Answer:
3 hours
Step-by-step explanation:
50+12h=86
-50 on both sides
12h=36
divide by 12 on both sides
h=3
For this case we have:
By properties of the radicals 
So:
.
Now, for power properties we have:
Thus, 
So:
in its radical form
Answer:
in its simplest form.
in its radical form
I don't know for sure I'm going to ace grade next year but I know that you you need to put the coefficients with the same variable together and the variable next to the coefficients and multiply or add or divide or subtract them and you get your answer and this is just 7th grade math I'm relying on

Answer:
p = 
, q = 9
Step-by-step explanation:
4x² + 12x ( factor out 4 from each term )
= 4(x² + 3x)
Using the method of completing the square
add/subtract ( half the coefficient of the x- term)² to x² + 3x
= 4(x² + 2( )x + 
- )
= 4(x + )² - 4 ×
= 4(x + )² - 9
