The expression equivalent to (3y+8x)+(4x-8y)

= 12x - 5y

Step-by-step explanation:

Given that:

=(3y+8x)+(4x-8y)

Now simplify by removing brackets:

= 3y + 8x + 4x - 8y

Add the same terms:

= 12x - 5y

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.
