The perimeter of a rectangle is 8\left(2x+1\right)8(2x+1) inches. If the width of the rectangle is 3x+43x+4 inches and length is 4x+34x+3 inches, what are the dimensions and area of the rectangle? width = inches

length = inches

area = square inches

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.
