An apartment rents for $800 a month the monthly rent is expected to increase $15 each year what will the rent at the end of the
Nataly [62]
To find this you would do 800 + 15x where x is the amount of years. 

For 9 years it would be 800 + 15(9) which is 800 + 135. 

At the end of 9 years, the apartment's rent would be $935. I hope that's utilities included because... yikes...

What is the completely factor form of x4+8x2-9
Mademuasel [1]
It takes some trial and error

To find the factored form, you know that the format will look like

 (x^n +/- a) (x^n +/- b)  

Since the expanded form has x^4, the first part of each expression in parentheses will be x^2  because x^2 * x^2 will give you x^4

Then you have to figure out, how will you get -9 in the expanded form? The "a" and "b" parts of each expression will have to multiply to equal -9.

Factors of -9 will be -3*3 or -1*9 or -9*1

Also, consider the 8x^2 part - as it relates to finding the factors of 9. The parts of the expression that result in  8x^2  in the expanded form ...

a*x^2 + b*x^2 = 8x^2

If you think about this, you know the a and b will  = -1 and 9 because you also have to add the expressions with x^2 to get 8x^2, and 3 and 3 would not give you the 8x^2 and neither would nor would -9 and 1.

Final factored form is

(x^2 - 1) (x^2 + 9)

Brooke has scores of 84, 72, 90, 95, and 87 on her first five quizzes. After taking the sixth quiz, Brooke’s mean score increase
OlgaM077 [116]

Answer:

90, 86, 92, 89

Step-by-step explanation:

The mean of her first five quiz scores is found by adding the scores together and dividing by 5:

(84+72+90+95+87)/5 = 428/5 = 85.6

Any value higher than this mean for the sixth quiz score will raise the overall mean; any value below this mean for the sixth quiz score will lower the overall mean.  This means the values that could increase her mean are 90, 86, 92 and 89.
