Answer:
yup
Explanation:
when there's a variable without a number in front of it it means that it equals 1. x+x+x+x=4x
Yes
x+x+x+x is added four times, which is equivalent to multiplying 4 times x, or 4x.
If we were to substitute any number in for x, we would get the same number from both expressions
Let's say x=4
x+x+x+x
4+4+4+4
16
4x
4*4
