Answer: D.) 102 kilometres per hour
Step-by-step explanation:
The car travels 34 kilometres in 20 minutes, to find the rate at which the car travels in kilometres per hour, we find convert the time taken (given in minutes) to travel this 34 kilometres to hours.
By doing this, 20 minutes = (20/60) hours = 1/3 hours.
Now to determine the rate, the motion Formula is given by:
Rate of travel = distance/time.
Rate = 34 / (1/3)
Rate = 34 * 3
Rate = 102 kilometres per hour.

Answer:
x^3+9x^2-3x^2-3
Step-by-step explanation:
You can use a various of methods but when you use the box method you multiply each separately.
Like you would multiply x² by x, 8x by x, -3 by x (thats the first row)
x² by 1, 8x by 1, -3 by 1 ( for the second row)
Then you get those final variables and combine like terms getting the answer above
You start by plugging in x=-2 into f(x)
f(-2) = 3^-2
Which gives you
f(-2) = 1/3^2 since negative exponents change the number to a dividend.
Then you square the 3
f(-2) = 1/9 or .111 repeating
