Answer:

-4x^2 + 3x +1 & it would be C. quadratic trinomial

Step-by-step explanation:

1: <u>Remove the parenthesis. Switch the -1 to a +1</u>.

8x^2 + 3x - 12x^2+1

2: <u>Simply the equation</u>.

8x^2 + 3x - 12x^2+1

 (2a. Group like terms)

= 8x^2 -12x^2+3x+1

 (2b. Add the similar elements)

= -4x^2 + 3x + 1

So you would minus 12x^2 and 8x^2 to get 4x^2!

Find the savings plan balance after 3 years with an APR of 7​% and monthly payments of ​$150.
Citrus2011 [14]

Answer:

The balance is $5989.5

Step-by-step explanation:

The savings plan balance is given by the following formula:

A = P*\left[\frac{(1 + \frac{APR}{n})^{n*Y} - 1}{\frac{APR}{n}}\right]

In which A is the savings plan balance, P is the monthly payment, APR is the annual percentage rate(decimal), n is the number of payments per year and Y is the number of years.

In this problem, we have that

Find the savings plan balance after 3 years with an APR of 7​% and monthly payments of ​$150.

So we have to find A when P = 150, APR = 0.07, n = 12, Y = 3.

So

A = P*\left[\frac{(1 + \frac{APR}{n})^{n*Y} - 1}{\frac{APR}{n}}\right]

A = 150*\left[\frac{(1 + \frac{0.07}{12})^{12*3} - 1}{\frac{0.07}{12}}\right]

A = 5989.5

The balance is $5989.5

Inside parenthesis

1/1=1

(replace it with that)

Open parenthesis

a=2-1-b

simplify numbers

a=1-b

isolate b

a-1=-b

multiple each side by negative 1

1-a=b

For a polynomial P(x), the quotient P(x)/(x-2) has a remainder of 12. What is the value of P(2)? Please explain. Thanks :)
RoseWind [281]

Answer:

12

Step-by-step explanation:

P(x) has infinitely many solutions, but I am going to find the easiest one, which would be a linear equation.

First, notice that x-2 perfectly divides into itself.

Then, if you add 12 to x-2, you will end up with a remainder of 12. Therefore, P(x) would be x-2+12 = x+10.

Now that we know P(x), we can directly plugin 2 to find out P(2):

2+10 = 12

Therefore, P(2) = 12.
