Answer:
The answer should be C) 4x + 5x = 180
Step-by-step explanation:
Let's start by moving all like terms to their own sides:
-18 = -3x + 6
3x = 6 + 18
3x = 24
x = 8
Answer:
The first step is
Take the square root of both sides of the equation
Step-by-step explanation:
we have

Solve for x
step 1
Take square root both sides

the solutions are
and 
therefore
The first step is
Take the square root of both sides of the equation
The function is undefinded if the denominator, x-5, equals 0.
So

.
The domain is

.
In interval notation, this is (-infinity, 5) u (5, infinity).
