Writing Expressions to Represent Volume
Charles begins finding the volume of a trapezoidal prism
using the formula A = (61+b)h to find the prism's base
area.
Which expression can be used to represent the volume
of the trapezoidal prism?
282 + 6x2
83 +6x2
x2 + 3x2
© 2x3 + 3x2
x+4
A = =((x + 4) + (x + 2))x
A = {(2x+6)x
A = (x + 3)x
A = x² + 3x

step-by-step explanation:

area = length x width

length = 2 x width

32 = 2 x width x width

32 = 2 x width^2

36 = width ^2  

width = 6

length = 12

area is 32

perimeter = 2 x 12 + 2 x 6 = 24 + 12 = 36

step-by-step explanation:

answer: the price of one pound cabbage = $ 0.8

the point (10,8) represents that the cost of 10 pounds cabbage is $ 8

step-by-step explanation:

since, here is a proportional relation between the number of pounds of cabbage (x) and the price in dollars (y).

therefore, we can write,

⇒ y = k x

where k is the constant of proportionality.

now, point (5,4) is in the line.

thus, it will satisfies the above equation of line.

⇒ 4 = 5 k

⇒ k = 0.8

thus, the equation of the line is,

y = 0.8 x

a) for x = 1,

y = 0.8

therefore, the cost of one pound of cabbage is 0.8 dollars.

b) in the below graph (10,8) represents that the cost of 10 pounds of cabbage is 8 dollars.

their is no graph showing
