Question

Which expression is represented by the model?

A. X-3
B. X+3
C. -X-3

Answer 1

first we know that the X is negative so we can ignore number A and B because they are positive.

Then we are left with two solutions and if you referred to the picture we know that whatever comes after has to be positive

So the correct answer is D

Answer 2
