Answer:
10 years old
Step-by-step explanation:
let his age be x , then in 20 years
x + 20 = 3x ( subtract x from both sides )
20 = 2x ( divide both sides by 2 )
10 = x

Assume that this number is n.
Difference between two number means the subtraction between them.
Therefore, "<span>The difference between a number and 12 is 20" means that when subtracting these two numbers, the result is 20.
Since the question did not mention which number is greater, therefore, we have two ways to write the equation.
These two ways are as follows:
x - 12 = 20, and
12 - x = 20

Remark
Interesting detail.
Origami Paper is square -- perfectly.
So the properties listed will be related to a square.
Givens
Area = 35 in^2
Formulas
Area = s^2 where s is the length of 1 side.
Perimeter = 4s
Solution
<u>Area = s^2 = 35</u>
s^2 = 35 Take the square root of both sides.
√s^2 = √35
s = 5.91
<u>Perimeter = 4s</u>
s = 5.91
Perimeter = 4*5.91
Perimeter = 23.66
The way the question is worded, the answer you should submit is
Perimeter = 4 * √35
