Answer:
An equivalent expression to 54+18x, using the distributive property is 18(3+x)
Explanation:
In the problem we have the binomial (54+18x), and we are asked to use the distributive property, this means that we can find a factor wich is distributed in both terms of the binomial.
We know that any number, or in this case any polinomial (or binomial), can be multiplied times 1 and will stay the same number, and we only need to write this 1 in a way that could resolve our problem, in particular we can say that

then we can distribute the denominator, so we calculate:

And the equivalent expression to (54+18x) is 18(3+x).
