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.

an advantage of the standard deviation is that it increases as the dispersion of the data increases. e. the interquartile range is preferred when the data are not skewed or no have outliers. an advantage of the standard deviation is that it uses all the observations in its computation.
