Which expressions are equivalent to x+x+x + 2 ? choose 2 answers: a 3x + 2 b 3 + 2x c 3(x+2) d 2(x+1)+x e 5x

        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:

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

By rearrangement of like terms, we have:

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

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.

his chances of getting a coin of higher value is 4/19

step-by-step explanation:

you can first factor out the n to get n(1+5). we know that 1+5 is 6, so we just have 6n.
