Answer:
1
Step-by-step explanation:
Scientific notation is the way that scientists easily handle very large numbers or very small numbers. For example, instead of writing 0.0000000056, we write 5.6 x 10-9. So, how does this work?
We can think of 5.6 x 10-9 as the product of two numbers: 5.6 (the digit term) and 10-9 (the exponential term).
Here are some examples of scientific notation
Set the length of the base as x, the two equal sides are then 4x each, so the perimeter is x+4x+4x=9x
Answer:
10x + 9
Step-by-step explanation:
-1 - (-10x - 10)
Distribute.
-1 + 10x + 10
10x + 9
Range: 16 (20 - 4)
Median: 9 (average 8 and 10)
Mean: 9.5 (average all the numbers)
