Answer:
Now, Mr Lee's age is 40 years, his son's age is 13 years.
Step-by-step explanation:
<u>4 years ago:</u>
Son's age = x years
Mr. Lee age = 4x years
<u>Now:</u>
Son's age = x + 4 years
Mr. Lee age = 4x + 4 years
The sum of the ages of Mr Lee and his son is 53 now, so

Now, Mr Lee's age is 40 years, his son's age is 13 years.
So (x + 5)*3 - 15 = 42
so the answer is
42 + 15 = 15 + 3x
so solving for x:
x = 14
Answer:
Solving the radical
we get 
Step-by-step explanation:
We need to simplify the radical: 
Prime factors of 18 are: 2x3x3
Replacing
with its factors

We know that 

Multiplying
with terms inside the bracket

We know that 

So, solving the radical
we get
