Answer 1

This looks like a regular equation with substitution. so it would be
5(2) + 2(5) + 1

10 + 10 + 1

21.

If theres another way of going about doing this please inform me :]

Answer 2

The value of the expression for N=5 is 36.

Explanation:

Consider the provided expression.

`N^2 + 2N + 1`

We need to solve the expression for N=5.

Substitute the value of N=5 in the above expression as shown:

`N^2 + 2N + 1`

`5^2 + 2(5) + 1`

`25 + 10 + 1`

`36`

Hence, the value of the expression for N=5 is 36.
