(i will give brainlisest answer) what is simplified expression for

hello there!

i am unable to find an answer that connects to one of your options but perhaps my calculations will allow you to achieve said answer.

-6x + 5y + 2, x + y

hope i !

have a great day.

answer:

c. 7y-4x

-3(2x-y)+2x+2(x+y)

we first need to distribute to get rid of both parenthesis.

so first one will be -3 (2x-y)

we multiply -3 and 2x

and

-y and -3

-3*2x= -6x

-y*-3=3y ( note a neativge multiplied by a neative equals a positive)

so we will write it as

-3x+3y+2y+2(x+y)

now we need distribute number closest to the parentesis (x+y).

that number is 2  

2*x= 2x

2*y= 2y

so we rewirte expression as

-6x+3y+2y+2x+2y

now we need to simplify.

to do so we need to combine like terms

combine liked terms means to add or subtract the like terms in an expression.

so -6x and 2x are liked terms 2x is positive so we add

-6x+2x=-4x

3y and 2y and 2y are liked terms

3y+2y+2y= 7y

so once your done it will look like

-4x+7y

we need to put into standard form basically big num first smaller last

7y-4x

d. millimeters per hour.

step-by-step explanation:

we are given that,

carlo used a rain gauge to measure the amount of water his lawn is receiving from the sprinklers.

since, according to the options, we see that,

water cannot be measured by 'miles per hour', 'meters per second' and 'grams per seconds'.

we get that, the water can be measured by 'millimeters per hour'.

hence, the appropriate rate for describing the amount of water is 'millimeters per hour'.
