Question

How much is 5a(6b+12)

Answer 1

5a (6b+12)

5a*6b+5a*12

30ab+60a
 This is the answer

Answer 2

When writing an expression in expanded form, we just need to multiply what's outside the parentheses by everything that is inside the parentheses.

5a (6b + 12)

(5a * 6b) + (5a * 12)

30ab + 60a

And that is our answer.
5a (6b + 12) in expanded form is 30ab + 60a.
Hope that helped =)
