Answer:
I think the answers is 27, just add all of those squares.
Mary = 3x
Seth = X
If we know that Mary is three times older than Seth, we can set this up into an equation.
3x + x = 76
Now, we can simplify on the left side by adding the Xs together.
4x = 76
X = 19
Therefore, Seth is 19 years old and Mary is 57 years old.

One way to simplify 3^2 x 3^5 is to add the exponents. In your case you would add ^3 + ^5 which equals ^7. You keep the whole number, 3, the same. Thus, your answer would be 3^7.
Hope this helps! :) (Don't forget Brainliest)
