3x2 - 5x + 2 5x² – x-6
Which of the following is the sum of the two
polynomials shown above?
A) 8x2 - 7x - 4
B) 8x² + 7x - 4
C) 8x - 7x² - 4
D) 8x4+ 7x2 - 4

This qn is mistake i think so while addind this 2 eqn the ans is 8x2-6x-4

the monthly balance will be $75,000

54 km / hours

step-by-step explanation:

we need to convert seconds to hours

60 seconds = 1 minutes

60 minutes = 1hour

15 m         60 second   60 minutes

  * *         = 54000 meters/ hour

second     1 minute             1 hour

now we need to convert meters to km

1000 m = 1 km

54000 m       1 km

*   = 54 km / hours

hour               1000m
