Answer:
16x² - 8x + 8
Step-by-step explanation:
f(x)=4x-1
g(x)=x²+7
g(f(x)) = g(4x-1) = (4x - 1)² + 7 = 16x² - 2*4x*1 +1² + 7= 16x² - 8x + 8
The question is incomplete. Add the remaining info
10 meters per second is the correct answer
Here's why:
10 miles per minute is 600mph
10 centimeters per hour is
0.000062mph
10 kilometers per hour is 22369mph
Here in this case the answer is "a". The way to find the percentage is to add all the numbers you have which is $49. And then you need to use it to divide it with the percentage you need for the number. Which in this case you are searching for shoelaces and it $4. So you divide the cose of the shoelaces $4 to the total amount $49. And then you multiply by 100 to get the percentage. If you round it off the the tenth place you should get 8.2%
2017 = 2 hrs x 60 mins = 120 mins
2016 = 8/11 x 120 mins = 87.27 mins
2015 = 9/12 x 120 mins = 90 mins
Therefore, Fatema ran the fastest in 2016.
