Answer 1

Hello :)

there are multiple ways to do this

for example, if you were to not look at any of the options, what answer would you get from just
5*(2 + 7) = ?

Answer 2

if you're not comfortable with the distributive property yet, you can do
5*(2 + 7) = 5 * 9 = 45

Answer 3

then

we can simplify the rest of the options and see which one equals 45

Answer 4

Just distribute.

5(2 + 7)
10 + 35
45
