Answer: -13x^2 + 10x + 4

Step-by-step explanation:

group all of the same variables together to simplify the equation.

-7 - 6 = -13 // the x^2 value

-5 + 15 = 10 // the x value

4 is the only number without an exponent so leave it alone.

For the past 100 days hunter ran an average of 6.8 kilometers each day.(a)how many kilometers has he run in the last 100 days? (
myrzilka [38]

Answer:

(a) 680 km

(b) 680000 m

Step-by-step explanation:

(a) Distance run by hunter every day = 6.8 km

Total number of days under consideration = 100

So the total distance covered by the hunter = \[6.8 * 100\]


= 680 km

The hunter ran 680 km in the last 100 days.

(b) Converting this value to meters:

1 km = 1000 m

=> 680 km = 680 * 1000 m

= 680000 m

The equivalent distance run by the hunter when converted to meters is 680000 meters.
