First let's find how much <em>7(4+9)</em> is.

Using the order of operations (PEMDAS)...

7(4+9)
7 · 13
91

Now let's go through each answer, and find one that adds up to 91.

28 + 9 = 37
Nope!

28 + 63 = 91
Yep!

The answer is 28 + 63 :)

Hopefully this helps! If you have any more questions or don't understand, feel free to DM me, and I'll get back to you ASAP! :)
