Like terms are going to have the EXACT same variables....or they can just be constants with no variables.
x^2 and 3x^2 are like terms
x^2 and x^3 are not like terms
8 and 9 are like terms
8x and 9y are not like terms
so ur like terms in ur problem are : 2y^3 and y^3
area of floor = length * width
length =18 feet
width =12 feet
area =12*18 = 216 feet square
Since they have the same base we can just add all the exponents
-3+ 10= 7
keep the base so the answer is
12^7
$20
Step-by-step explanation:
I'm high a.f. but I'm certain it's $20
