A coordinate plane with the x-axis labeled Blueberries (in pints) and the y-axis labeled Cost (in dollars) shows a line going through (0, 0) and (5, 17).
<h3>What is directly proportional?</h3>It is defined as the relationship between two quantities as one quantity increases the other quantity also increases and vice versa.
It is given that there is a proportional relationship between cost and pints of blueberries as,
Blueberries (in pints) 2 5
Cost (in dollars) 6.80 17
17/6.80 = 5/2
As we draw the graph and analyze each option one by one we get the graph shown by the statement C following the given proportional relationship.
Thus, a coordinate plane with the x-axis labeled Blueberries (in pints) and the y-axis labeled Cost (in dollars) shows a line going through (0, 0) and (5, 17).

Answer:
a) the area of a square is in terms of x is
centimeter square
b)The length of the rectangle is l = (x+1)
l = 7+1 =8 cm
The width of the rectangle is w = [(x+1)-5]
w = (7+1)-5 =3 cm
Step-by-step explanation:
a) the area of a square is in terms of x is
area of square is
=
b) Given length is l = (x+1) cm and
the width is 5 cm less than its length.
so we have take width is w = (x+1)-5 cm
Given area of triangle is 24 cm
Area of rectangle = length X width
24 = (x+1)(x+1 -5 )
now simplification
apply (a+b)^2 = a^2+2 a b+b^2
now find factors of 28 = 7 X 4 is
x = -4 and x=7
there fore you have to choose x = 7
The length of the rectangle is l = (x+1)
l = 7+1 =8
The width of the rectangle is w = [(x+1)-5]
w = (7+1)-5 = 3
<u>Verification:-</u>
Given area of rectangle = 24 = 8 X 3
24 =24
so we can not choose x=-4
we have to choose x =7 only
