Answer:
c = 36
Step-by-step explanation:
x^2 + 12x
Take the coefficient of x
12
divide by 2
12/2 =6
square it
6^2 = 36
Add this
c=36
Answer:
x = 9(4)-34 = 2
Step-by-step explanation:
X-10>15.........................................
X + 8 >= 18
(>= means greater than or equal to)
x + 8 - 8 >= 18 - 8
x >= 10
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
