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.

Answer:
w==77
Step-by-step explanation:
The sum of the 2 opposite interior angles equals the exterior angle.
w-36 +w-20=w+21
combine like terms: 2w-56=w+21
subtract w from both sides: w-56=21
add 56 to both sides: <u>w=77</u>
