The length of a rectangle is 8 centimeters, and the area of the rectangle is 72 square centimeters. what is the width of the rectangle?

The width if the rectangle is 9 sq. cm.

Step-by-step explanation:

a = wl, which means area equals length times width, so to find the width when you have the length and area you need to divide the area by the length.

72/8 = 9

This exact method will also work if you have the width and not the length.

Hope this helps!

y=-2.5x+12.5

step-by-step explanation:

5y=2x+10

y=0.4x+2

slope=-2.5

5=-2.5*3+b

b=12.5

step-by-step explanation:

let's assume

number of candles set =x

price of of x candles =p(x)

we are given

a candle maker prices one set of scented candles at $10 and sells an average of 200 sets each week

so, we get point as (200,10)

he finds that when he reduces the price by $1, he then sells 50 more candle sets each week

so, we can find slope

now, we can use point slope form of line

now, we can plug values

we can use point

and find b

now, we can plug it back

and we get

now, we can find revenue

we know that

revenue = price*quantity

so, we get
