Answer 1

The answer is E.  You first take the 3 and 1 and treat it separately.  Then use that answer as (answer) and 1.  Kinda hard to explain.

Answer 2

hahah SAT

good lucK!

answer is E

Answer 3

The answer is E 183

What you have to do first is to understand the expression. x (triangle) y is the expression that = x^2*xy*y^2

All you have to do is order of operations which means find out what the one in the parenthesis is which is 3(triangle)1, plug that into the x^2 equation to get 13.

Then take the 13 and plug it into the other new equation 13(triangle) 1, and solve the x^2 to get an answer of 183
