Okay so you are going to really just add 30 + 9 here and that means you have 30 tens and 9 ones or a 30 in the tens place and a 9 in the ones place.
I hope i broke that down well enough.
I hope this helped :)
N + 4 - 9 - 5
n + (4 - 9 - 5) collect like terms
n - 10 simplify
hope this is what you're looking for. hope this helps, God bless!
Nope you cannot write that in simplest form
Answer:
13.4
Step-by-step explanation:
13.4 is the answer because a perimeter is the total distance around the shape
when you take 152.6 and subtract all of the different sides your left with the length of the last side
152.6 - 13.1 - 13.1 - 9.3 - 54.2 - 9.3 - 27.1 - 13.1 = 13.4
