I'm assuming this is a math question and all the tents equal the same thing, so to find the price for one tent, we would divide 40/3
Each tent is about $13.33
Answer:
C. 26 Inches
Step-by-step explanation:
Using process of elimination you can tell the answer. 26*(13+3)=416

Least Common Multiplier(LCM)
The least or smallest common multiple of any two or more given natural numbers are termed as LCM. For example, LCM of 10, 15, and 20 is 60.

Property used: 'Power of a power'
We can raise a power to a power
(x^2)4=(x⋅x)⋅(x⋅x)⋅(x⋅x)⋅(x⋅x)=x^8
This is called the power of a power property and says that to find a power of a power you just have to multiply the exponents.
So what are we trying to find the reduced fraction or inverse operation
