The  length of a rectangle is 2 less than twice its width. The area is 144 squared centimeters. Which quadratic equation in standard form correctly models the situation, where w represents the width of the rectangle

The quadratic equation which correctly models the situation is,

Let us consider that width is w.

Given that The length of a rectangle is 2 less than twice its width.

 Area of rectangle (A)

The area is 144 squared centimeters.

Hence, the quadratic equation which correctly models the situation is,

w² - w - 72 = 0

Step-by-step explanation:

l = 2w - 2

A = 144

A = l * w

A = (2w - 2)w

144 = 2w² - 2w

0 = 2w² - 2w - 144

2w² - 2w - 144 = 0 (divide all by 2)

w² - w - 72 = 0

a box 3 3/4 feet long or 4+ feet.

step-by-step explanation:

constant of proportionality = 3 and the equation is c = 3p.

step-by-step explanation:

c = kp   where c = amount of caffeine in mg., p = oz of pepsi and k is the constant of proportionality.

substituting the values given:

24 = 8k

k = 3.

the same value of k will be obtained if we substitute the other given values.
