Answer:
[tex]55[/tex] or [tex]47[/tex]
Step-by-step explanation:
For the equation, I will give you two options of which equation you have, the first one is [tex]5 \times (2+x^2)[/tex] and the other is [tex]2 + 5x^2[/tex].
[tex]5 \times (2+ 3^2)\\5 \times (2+ 9)\\5 \times (11) = 55[/tex]
The second equation you just have to repeat the substitution:
[tex]2 + 5 \times (3^2)\\2 + 5 \times (9)\\2 + 45 = 47[/tex]
