Arectangular swimming pool had a length twice as long as it’s width. the pool has a sidewalk around it that is 2 feet wide. write an expression that would you find the area of the pool and it’s sidewalk.

Area =  

Step-by-step explanation:

We let the width of the pool be "w"

We know the length is twice as long as width, so the length is:

2w

So,

Width = w

Length = 2w

Since a sidewalk with 2 feet width goes around the pool completely, the area enclosed by pool + sidewalk would have 2 feet around it, so its length and width would be:

Width = w + 2 + 2 = w + 4

Length = 2w + 2 + 2 = 2w + 4

The area of a rectangular region is always length * width, so the expression for area of pool and sidewalk would be:

If we let the width of the swimming pool be "w", the expression for the area of pool and sidewalk is:

Area =  

the answer is 150.6

step-by-step explanation:

you multiply .02 by 30 and get .6.

and then you multiply 5.00 by 30 and get 150.

hope this !

the speed is   miles per hour > is false

step-by-step explanation:

we know that  

a relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form or

in a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin

the graph shown in the figure represent a direct variation

the slope of the line represent the speed

for the point

substitute the values of x and y

the linear equation is equal to

statements

case a) it takes hours to go miles

the statement is true

because

substitute

for

find the value of y in the linear equation

> is correct

case b) the speed is   miles per hour

the statement is false

because the speed is

case c) the unit rate for the trip is

the statement is true

because the speed is equal to the slope of the linear equation

case d) it took minutes to go the first miles

the statement is true

because

substitute

for

find the value of y in the linear equation

> is correct
