Answer:
C =3.33x
Step-by-step explanation:
The cost of 1 barrette is
9.99/3 sine it is 9.99 for 3 barrettes
or 3.33 per barrette
We want x barrettes
or 3.33*x
C is the total cost
C =3.33x
Length = 13 = (x + 3)
Width = 14 = (x + 4)
x2 + 7x + 12 = area of the rectangle
can be factored into
(x + 3)(x + 4)
Let L = one of the factors (x + 3)
Let W = the other factor (x + 4)
If x = 10 then
(10 + 3) = 13 = L
(10 + 4) = 14 = W
Checking this can be checked a couple of ways
Plug x = 10 into the original equation
x2 + 7x + 12
102 + 7(10) 12 = 100 + 70 + 12 = 182 = Area
Multiplty the factors
L x W = 13 x 14 = 182 = Area

I think it is not because it’s also not proportional and they are basically identical except for what b is equal to
