40,000 is the the value of 4 in the 10,000
Answer:
1.36mph
Step-by-step explanation:
The escalator is moving at 2ft/s, lets convert this to miles/second.
2ft/s = 0.000378788miles/s.
Now that we have the miles/second lets multiply this value by 3600 to get the miles/h, because there are 3600 seconds in an hour.
2ft/s=1.3636368miles/h
Or approximately 1.36miles/h.
Answer:
The first one, you cannot factor because the two values do not share any common factors. Hence, the answer would just be:
a. 51x-25
The other one, we can factorise to:
b. 3x(4-x)
Step-by-step explanation:
For the second option:
Common factor between 12x and 3x^2 is 3x.
Take this out to the front, we are left with:
3x(4-x)
