We can solve for by using the quadratic formula:
AND
Let's identify our values:
Plug in the values and simplify.
Your final answers are:
AND
Well on the second picture your answer is A
2. is B
Answer:
v = 72 km/h
Step-by-step explanation:
Given that,
The distance covered by the Patrick, d = 288 km
Time taken, t = 4 hours
We need to find the average speed of Patrick. We know that the average speed of an object is equal to the total distance covered divided by total time taken. Let it is v. So,
So, his average speed is equal to 72 km/h.
I believe it’s B because everything equals 180 and then 180-70=10
5x10 is tens place and 5x.1 is tenths place if i that helps :]
