Answer:

Step-by-step explanation:

A is not correct. A trapezoid does not have 4 equal sides.

B is not correct. Same reason as A even if the trapezoid is isosceles.

C is not correct. A square has 4 equal sides and 2 sets of parallel lines and 1 right angle. That is not what this figure looks like.

D is the correct answer.

E is incorrect. A rectangle has 2 pairs of equal sides and two sets of opposite sides that are equal and parallel. It also has at least 1 right angle.

The original figure has none of these things.

Profit is the difference between revenue and cost. The revenue, in dollar, of company that manufactures television can be modele

Anon25 [30]

Answer:

The profit in this case is equal to $50,700.

Step-by-step explanation:

As the problem stated profit is the difference between revenue and cost, in this case we have:

$revenue(x) = 3x^2 + 180x$

$cost(x) = 3x^2 - 160x + 300$

So the profit will be the difference between these two functions.

$profit(x) = revenue(x) - cost(x)\\profit(x) = 3x^2 + 180x - 3x^2 + 160x - 300\\profit(x) = 340x - 300$

In order to find the profit when 150 televisions are sold we need to make x equal 150.

$profit(150) = 340*150 - 300\\profit(150) = 51000 - 300 = 50700$

The profit in this case is equal to $50,700.

olasank [31]

Answer: r=4

What you do is subtract 12 from itself and from -24 then you have -9r=-36. Then you take -9r and divide it -9 then do the same to -36 and you get 4 :)
