Find the sum of 3x + y , - 4x -2y

Answers

Answer:

(-x-y)

Step-by-step explanation:

Given data

First expression = ( 3x + y)

Second expression = (-4x -2y)

Add the two expresssion

= ( 3x + y)+ (-4x -2y)

Open bracket

=3x+y-4x-2y

collect like terms

=3x-4x+y-2y

=-x-y

Hence the result is (-x-y)

A hallway measuring 90 feet x 7 feet requires 1/2 a fluid ounce of cleaning solution per square foot. How much cleaning solution is required to clean the hallway?

Answers

First, find the area of the hallway.

$Area=length*width$

$A=90*7$

$A=630$

Now you know there are 630 square feet to be cleaned. To find the amount of cleaning solution needed, multiply this number by 1/2.

$Solution=area* (1)/(2)$

$S=630* (1)/(2)$

$S= (630)/(2)$

$S=315$

Answer: 315 fluid ounces

$90*7 = 630ft ^(2) \n \n 1/2 floz ->1 ft^(2) \n \n 630/2=315 \n\n\boxed{315}$
