Which is the first step in simplifying the expression 2(x + 3) + 5?
2x + 2(3) + 5
2x + 3 + 5
2 + x + 3 + 5
2(5) + x + 3

2x + 2(3) + 5

Step-by-step explanation:

The first step in this type of expression is to develop the parenthesis, that is, to multiply the components within the parenthesis by the term that is just outside it.

In this case the first step is as follows:

2x + 2(3) +5

which is to multiply the 2 by the x and the same 2 by the 3 to remove the parenthesis, so the answer is the first option.

i think it's b

step-by-step explanation:

because the graph is 2 above (0,0)

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer
