X^2 - 9x - 36 = 0

Note that one possible set of factors is (x-12)(x+3).  Why?  Because (-12)(3) = -36 and -12x + 3x = -9x.

PLEASE HELP!!! Julianne opens a dance studio. Her start-up costs for the building, advertising, and supplies total $52,000. Each
givi [52]

Alright, lets gets started.

Jullianne's start-up costs for the building, advertising, and supplies total $52,000.

she spends $680 on operating costs on daily basis.

Means Suppose the days d, the operating cost will be= 680 d

This cost will be added in her start up cost.

The earning for d days will be = 960 d

So, part A :

5200 + 680 d < 960 d


Now suppose after d days, she will start making profit means, after d days, her cost will be equal to her earning.

So, part B:

5200 + 680 d = 960 d

Subtracting 680 d from both sides

5200 + 680 d - 680 d = 960 d - 680 d

5200 = 280 d

Dividing 280 in both sides

d = \frac{5200}{280}=18.6

Means after 19 days, she will start making profit.   :    Answer

Hope it will help :)
