Correct answer only ! george has opened a new store and he is monitoring its success closely. he has found that this store’s revenue each month can be modeled by r(x)=x^2+6x+10 where x represents the number of months since the store opens the doors and r(x) is measured in hundreds of dollars. he has also found that his expenses each month can be modeled by c(x)=x^2−4x+5 where x represents the number of months the store has been open and c(x) is measured in hundreds of dollars. what does (r−c)(4) mean about george's new store?

A. profit of $4500

Step-by-step explanation:

    r(x) = x² + 6x + 10

  - c(x) = x² - 4x + 5

(r - c)(x) =     10x + 5

(r - c)(4) = 10(4) + 5

           =  40 + 5

           = 45

(r - c)(x) represents the profit (in hundreds of dollars) in x months

(r - c)(4) represents the profit (in hundreds of dollars) in 4 months

So, the new store will have a profit of $4500 in 4 months

step-by-step explanation:

the probability is   .24

the first player had the highest probability of getting a silver marble

the game could be made fair by adding back the marble that was drawn after each draw
