The length of a rectangle is four times the width. the perimeter of the rectangle is 45 inches. write a system of equations that represents this problem. what is the area of the rectangle?

let width of rectangle=x

the length of a rectangle is four times the width.

length =4x

area =l*w = x*4x =4x²)

perimeter =2l +2w

perimeter = 2(x+4x)

45=2(5x)

10x=45

x=4.5

area =4x²=4(2.5)²=25

area = 25 in²

4+n=5

step-by-step explanation:

this is because the four is four hours and the n represents the 1 extra hour over the weekend.

b= i'm srry i don't know that one.

4+n=5 n=1 because if vernon plays 5 hours a week then 4+1=5 hours.

hope this : )

you didn't give me the choices, so i will just give you the graph so you can look at your choices and choose the right one.
