What is expression?
In mathematics, an expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context.
What is greatest common factor?
The greatest common factor (GCF) of a set of numbers is the largest factor that all the numbers share. For example, 12, 20, and 24 have two common factors: 2 and 4. The largest is 4, so we say that the GCF of 12, 20, and 24 is 4. GCF is often used to find common denominators.
According to question, Julio wants to rewrite 48 + 18 using the greatest common factor and the distributive property.
We have to find the correct expression.
Since, the the greatest common factor of both numbers is 6.
We have to divide both numbers by the GCF and we will get the numbers on the inside are 8 and 3.
Hence,[tex]6(8 + 3)[/tex] is the expression Julio should write.
