A = L * W
A = 2/5 * 3/5
A = 6/25 in^2
For this case we have:
By trigonometric property we have:

Where:


Substituting:

Clearing x we have:

Thus, the equation is:
Answer:

The two numbers are 28 and 29.
Since the denominator is the number on the bottom, we need to find a common denominator for a and 5a^2. Since a*5a is 5a^2, we have a common denominator - 5a^2! For the fractions, that means that since a*5a=5a^2, we have to multiply -7 by 5a to get -35a/5a^2-9/5a^2=(-35a-9)/5a^2
