Oliver has 2 pieces of rope that are each 3 1/2 ft long. he also has a piece of string that is 2 1/4 ft long. olivier needs to cut this string into 3 pieces that are all the same length to finish an art project. how long should each piece of string be?

This is the concept of arithmetic; given that a string was cut into 3 equal pieces.
The length of each piece will be:
[length of the string]*3
length of the string=2 1/4 ft=9/4 ft
thus the length will be:
9/4÷3
=9/4×1/3
=3/4 ft
thus we conclude that the length of each string will be 3/4 ft long

If the x is an x, then 4(12+23x^3) to simplify

But if it's a multiplication sign, then it's 324
