166
Step-by-step explanation:
Do the parathisis first
(2x12)=24
(5x6)=30
Then do
220-24-30=166
Wait so are the sides of the octagon 9 inches each or do we have to find that?
Hey there!
In order for you to find the one that is equivalent to the given expression is to COMBINE YOUR LIKE TERMS then work from there!
12q + q^2 - 8 + q = ?
(q^2) + (12q + q) + (-8)
q^2 = q^2 since it doesn't have any like term(s)
12q + q = 12q + 1q = 13q
-8 = -8 since it doesn't have any like term(s)
Put all the numbers we solved for in An equation and Thats your answer!
If you did it correctly you should have: q^2 + 13q - 8
Answer: q^2 + 13q - 8 ✅
Good luck on your assignment and enjoy your day!
