Answer:

P = 9

Step-by-step explanation:

When P = 9, we could multiply 9 to (2n+ 3).

We would get:

In the lab, Debra has two solutions that contain alcohol and is mixing them with each other. Solution A is 10% alcohol and Solut

Ivahew [28]

Answer:

800 mL

Step-by-step explanation:

Let b represent the amount of solution B added to 2400 mL of solution A. The total amount of alcohol (mL) in the mixture is ...

10%×2400 + 50%×b = 20%×(2400 +b)

multiplying by 100 to get rid of the % signs and simplifying, we have ...

24000 +50b = 48000 +20b

30b = 24000 . . . . . . . . . subtract 24000+20b

b = 800 . . . . . . . . . . . . . . divide by 30

Debra added 800 mL of 50% alcohol to her 2400 mL of 10% alcohol to make a 20% solution.

Ann [662]

<u>Corrected Question</u>

In the year 2009, the cost of a flat screen television can be modeled by the equation C = -10t^2 + 500 where t is the number of years since 2009. Factor this cost polynomial.

Answer:

$C=10(50-t^2)$

Using express exponents, you write C=10(50-t^2)

Step-by-step explanation:

To factor the cost polynomial, $C=-10t^2+500$ , we follow these steps.

Step 1: Determine the greatest common divisor of the terms in the polynomial

The terms in the polynomial are $-10t^2$ and 500$

The greatest common divisor of $-10t^2$ and 500$ is 10.

Step 2: Factor the polynomial by dividing each of the terms with the greatest common divisor obtained above.

$C=10\left(\dfrac{-10t^2}{10} +\dfrac{500}{10}\right)\\C=10(-t^2+50)\\$We can rewrite this as \\C=10(50-t^2)$
