Answer:
7 
Step-by-step explanation:
volume is length X width X height
since a cube has the same measurement for length, width, and height, the volume is found by multiplying
X
X ![\sqrt[3]{7}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B7%7D)
the answer is 7
Answer:
don't understand the full question
Answer:
only -7
Step-by-step explanation:
Just plug them in.
so for x=-7
So this one is extraneous
Then if you plug -3 in you get 1 = 1 so this one is not extraneous. if you need me to work this one out let me know.
I think
A. convert the time to seconds, so all the time are 7070sec and the total course to meter.
so 31300meter
Vector = TotalCourse÷total time
V=31300/7070=4.427157m/s
convert it to km/h so 4.427157×36÷10=
15.9377km/h
B. 45÷15.9377=2.823Hour
it means that around 2 Hour 48Minutes more.
i think the teacher need to simplify it
