Profit is the difference between revenue and cost. The revenue, in dollars, of a company that manufactures televisions, can be m

odeled by the polynomial 3x2 + 180x. The cost, in dollars, of producing the televisions can be modeled by 3x2 -160x + 300. The variable x is the number of televisions sold. If 150 televisions are sold, what is the profit?

Answer:

50,700

Step-by-step explanation:

3x^2 + 180x - (3x^2 - 160x + 300) = profit

3x^2 + 180x - 3x^2 + 160x - 300 = profit

340x - 300 = profit

so if 150 televisions are sold...x = 150

340(150) - 300 =

50,700 <==

When 3(2x + 5) is added to 2(2x − 4) the resulting expression is?
velikii [3]

Answer:

10x + 7

Step-by-step explanation:

3(2x + 5) added to 2(2x - 4) is the same as 3(2x +5) + 2(2x - 4)

Remember PEMDAS

P – Parentheses  (distribution)

E – Exponents

M – Multiplication

/D – Division  (whichever comes first from left to right)

A – Addition

/S – Subtraction (whichever comes first from left to right)

First, we will distribute the left side.

3(2x + 5)

3 * 2x = 6x

3 * 5 = 15

Add them together to get:

6x + 15

6x + 15 + 2(2x - 4)

We must now distribute the right side.

2 * 2x = 4x

2 * -4 = -8

Add them together to get:

4x  -8

We now have:

6x + 15 + 4x - 8

<u>Let's combine like terms.</u>

6x and 4x are like terms.

Combine: 6x + 4x = 10x

15 and -8 are like terms.

15 - 8 = 7

Now we have 10x + 7

Since 10 and 7 don't have any GCF, we have our answer.

10x + 7
