A rectangular water tank has the following dimensions: length = 2x
width = 2x - 6
height = x + 1

What is the volume of the tank expressed as a polynomial?

4x2 - 12x

2x2 - 4x - 6

4x3 - 8x2 - 12x

4x3 - 16x2 + 12x

List the sides of δrst in in ascending order (shortest to longest) if: a ∠r =x+28°, m∠s = 2x+16°, and m∠t = x+12°

Lin is writing an equation to model the proportional relationship between y, the total cost in dollars of downloading videos from a website, and x, the number of videos downloaded. she knows that the total cost to download 3 videos was $12. her work to find the equation is shown below. joylin’s work step 1 k= 3/12= 0.25 step 2 y= 0.25x where did joylin make her first error?
