In 1819, the united states purchased florida from spain for $5 × . the area of florida is about 6.6 × square miles. which key strokes on a calculator will give the cost the united states paid for each square mile of florida?

The keystroke on the calculator which give the  cost the United States paid for each square mile of Florida is division.

Step-by-step explanation:

Total Cost paid by United States for purchasing Florida from Spain = $5

Area of Florida = 6.6 square miles

If we need to find the cost of one square mile : Then we will divide the total area of Florida in square miles by the total cost of purchasing Florida

Hence, the keystroke on the calculator which give the  cost the United States paid for each square mile of Florida is division.

(x3 + 6x2 + 2x - 6) • (x - 1)

step-by-step explanation:

polynomial long division :

3.2     polynomial long division

dividing :   x4+5x3-4x2-8x+6

                              ("dividend")

by         :     x-1     ("divisor")

dividend     x4   +   5x3   -   4x2   -   8x   +   6

- divisor   * x3     x4   -   x3            

remainder         6x3   -   4x2   -   8x   +   6

- divisor   * 6x2         6x3   -   6x2        

remainder             2x2   -   8x   +   6

- divisor   * 2x1             2x2   -   2x    

remainder               -   6x   +   6

- divisor   * -6x0               -   6x   +   6

remainder                     0

quotient :   x3+6x2+2x-6   remainder:   0

76%

step-by-step explanation:

24% are dogs and the remaining is 76% because 100-24=76
