Using the formula of P(1 + r)^n = x where p represents the initial value, r represents the rate and n represents the number of years and x is our final output. We want to find P so we have to make it the subject of the equation.
1 + 0.04 = 1.04
1.04^18 = 2.025816515
Then divide the total amount by this to get 185,110.5454
Therefore the answer is $185,110.55
Hope this helps! :)
So to rewrite it so that we can find the side, we just need to isolate the a variable.

So firstly, divide by 6 on both sides of the equation: 
Next, square root each side, and your answer should be 
Answer:x = 56
Step-by-step explanation:
180-(60+64)=56
