<h3>
Answer: 5</h3>
=================================
Explanation:
Apply the difference of squares rule
x^2 - y^2 = (x-y)(x+y)
x^2 - y^2 = (5)(1)
x^2 - y^2 = 5
----------
Alternatively, you can solve the system
for x and y to get (x,y) = (3,-2).
Then compute x^2-y^2 = 3^2-(-2)^2 = 9-4 = 5
Hey there!
Here are the steps involved in answering this question:
1. Write 12 out of 32 as a fraction which is
