Answer:

(2x-1)

Step-by-step explanation:

Volume\ of\ the\ tank\ = 12x^3+20x^2-x-6\\Length\ of\ the\ tank\ = 3x+2\\Breadth\ of\ the\ tank\ = 2x+3\\Height\ of\ the\ tank\ = h\\We\ know\ that\ volume\ of\ a\ cuboid\ = lbh\\Hence, h= Volume / lb\\Here,\\Height\ of\ the\ tank= \frac{(12x^3+20x^2-x-6)}{(3x+2)(2x+3)} \\By\ factorising\ the\ volume\ through\ synthetic\ division\, \\we get,\\(12x^3+20x^2-x-6)= (3x+2)(2x+3)(2x-1)\\Hence, height= (2x-1)

Triangle UVW has a perimeter of 11.5 units. Solve for y.
Lina20 [59]

Answer:

The answer for y is 4 units

Step-by-step explanation:

The obvious question to ask in this situation is, “how many miles does Joseph travel on Mondays”? To compute, we each distance: 3 + 6 + 6 = 15.

Joseph travels 15 miles on Mondays.

Another way to work with this situation is to draw a shape that represents Joseph’s travel route and is labeled with the distance from one spot to another.

Notice that the shape made by Joseph’s route is that of a closed geometric figure with three sides (a triangle) (see figure 2). What we can ask about this shape is, “what is the perimeter of the triangle”?

Perimeter means “distance around a closed figure or shape” and to compute we add each length: 3 + 6 + 6 = 15

Our conclusion is the same as above: Joseph travels 15 miles on Mondays.

However, what we did was model the situation with a geometric shape and then apply a specific geometric concept (perimeter) to computer how far Joseph traveled.
