The blank space is found by dividing 36a^2 by 12, which is equal to 3a^2
To get to this answer you need to
1. divide the both sides of the equation by 12.
2. subtract 2b^2 from both sides.
You will see that the blank space equals 3a<span>^2 then</span>
Call Martha's age 5 years ago is x So Martha father's age five years ago is 7x
We have : 7x + 5 = 4(x + 5)
3x = 25+5=30 so x = 5 so Martha's present age is 10 and her's father's present age is 40
