Solve (16×^3-3×^2+43×-5)÷(×^2-2)
Oksana_A [137]

Answer:

3872/(x^2 - 2)

Step-by-step explanation:

Simplify the following:

(16^3 - 3^2 - 5×43)/(x^2 - 2)

3^2 = 9:

(16^3 - 9 - 5×43)/(x^2 - 2)

16^3 = 16×16^2:

(16×16^2 - 9 - 5×43)/(x^2 - 2)

| 1 | 6

× | 1 | 6

| 9 | 6

1 | 6 | 0

2 | 5 | 6:

(16×256 - 9 - 5×43)/(x^2 - 2)

16×256 = 4096:

(4096 - 9 - 5×43)/(x^2 - 2)

43 (-5) = -215:

(4096 - 9 + -215)/(x^2 - 2)

4096 - 9 - 215 = 3872:

Answer: 3872/(x^2 - 2)

If a car travels 792 feet in 12 seconds what is the speed of the car in miles per hour?
UkoKoshka [18]

Answer:

Step-by-step explanation:

1 mile contains 5280 feet

x mile contains 792 feet             Cross Multiply

5280 x = 792                               Divide by 5280

x = 792 / 5280

x = 0.15 miles

1 hour = 3600 seconds

Distance travelled in 12 sec = 0.15 miles

                                 3600 sec = x                       Cross Multiply

12x = 3600  * 0.15                                                  Combine

12x =  540                                                               Divide both sides by 12

12x/12 = 540/12

x = 45 miles / hour
