The image contains two mathematical expressions:

1. $4^2 + 2^2$
2. $(4 + 5) - 2$

Let's solve each expression step by step.

1. $4^2 + 2^2$

This expression involves two squares and their sum:

• $4^2 = 16$
• $2^2 = 4$

Adding them together: $16 + 4 = 20$

So, $4^2 + 2^2 = 20$.

2. $(4 + 5) - 2$

This expression involves a sum inside parentheses and then a subtraction:

• First, calculate the sum inside the parentheses: $4 + 5 = 9$
• Then subtract 2: $9 - 2 = 7$

So, $(4 + 5) - 2 = 7$.

Final Results:

• $4^2 + 2^2 = 20$
• $(4 + 5) - 2 = 7$
