Answer:

A and D

Step-by-step explanation:

Only Answers A and D are equivalent to the given expression.

In A we see the variable 'x' show up three times, and so we write 3x + 2.

In D, after performing the indicated multiplication, we have 2x + 2 + x, which condenses to 3x + 2.

        A mathematical expression is a finite arrangement of symbols and variables following a rule relating to the set of the finite variables.

From the given information:

  • x +x + x + 2
  • = 3x + 2

Also, we can have it has: 2(x+1) +x.

This is because if we simplify the above expression, we will arrive at 3x +2.

Let's solve:

The first thing we will want to do is to open the brackets

  • = 2(x+1) + x
  • = 2x + 2 + x

By rearrangement of like terms, we have:

  • = 2x + x + 2
  • = 3x +2

        Therefore, we can conclude that the mathematical expressions that are equivalent to x + x + x +2 are in Option A and D.
