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:

30 miles

step-by-step explanation:

we know that 60 seconds equals 1 minute and 60 minutes 1 hour

44 ft       60 sec     60 min     158400   ft

  *   *   =

1 sec       1 min       1 hour         hour

we know that there are 5280 ft per mile

158400   ft       1 mile         30 miles

  *   =

1   hour               5280 ft     1 hour

so in 1 hour   it can travel 30 miles
