What is the sumplified expression for -3(2x-y)+2y+2(x+y) A)8x+y

B)y-4x

c)7y-4x

D)-4x-y

pls guys if for a test

=−4x+7y

Let's simplify step-by-step.

−3(2x−y)+2y+2(x+y)

Distribute:

=(−3)(2x)+(−3)(−y)+2y+(2)(x)+(2)(y)

=−6x+3y+2y+2x+2y

Combine Like Terms:

=−6x+3y+2y+2x+2y

=(−6x+2x)+(3y+2y+2y)

=−4x+7y

=−4x+7y

hope i helped

solution:

as, mean is defined as sum of all the observations divided by total number of observations.

and , median is mid value of the data whether arranged in ascending order or descending order.

consider, roadsters:

2,3,4,5,6,7,8,9

mean =

also, median= , because number of observations is even, so median is mean of two mid values.

now, coming to bandits

2,3,4,5,6

mean =  

median = 4, as number of observations is odd.

so, roadsters has greater median as well mean than bandits.

→option a is true about the repairs performed on 2 types of cars:

bandits have lower median and mean than roadsters.
