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 :)
Answer:
6
Step-by-step explanation:
<u>Area of sq:</u>
A = bh
A = (2)(2)
A = 4
<u>Area of triangle:</u>
A = 1/2bh
A = 1/2(2)(2)
A = 2
<u>Combined:</u>
4 + 2 = 6
-20^3=-8000, so the real cube root of -8000 is -20.
