Answer:
16
Step-by-step explanation:
Let's start by substituting y=\greenD6y=6y, equals, start color #1fab54, 6, end color #1fab54 and x=\blueD5x=5x, equals, start color #11accd, 5, end color #11accd into the expression.
y^2-x^2y

−x

y, squared, minus, x, squared
\greenD6^2 -\blueD5^26

start color #1fab54, 6, end color #1fab54, squared, minus, start color #11accd, 5, end color #11accd, squared
Hint #22 / 3
Now we can simplify:
\begin{aligned}\greenD6^2 &-\blueD5^2\\ =\greenD{36}&-\blueD{25} \end{aligned}

−25
Hint #33 / 3
\greenD{36}-\blueD{25} = 1136−25=11
