You can prove this statement as follows:
Step-by-step explanation:
An odd integer is a number of the form
where
. Consider the following cases.
Case 1. If
is even we have:
.
If we denote by
we have that
.
Case 2. if
is odd we have:
.
If we denote by
we have that 
This result says that the remainder when we divide the square of any odd integer by 8 is 1.
Answer:
7/20
Step-by-step explanation:
given,
2r = 7/10
r= 7/10*1/2
r= 7/20
By the binomial theorem,

where

Then the coefficients of the
terms in the expansion are, in order from
to
,





Answer:
The answer is: 1, 2, and 6
Step-by-step explanation:
Answer:
4.5 meters
Step-by-step explanation:
The formula for the area of a rectangle is length x width. Using this formula, you can substitute the given information and find the area:
length x width = area
0.3km x 0.15km = area
0.045km = area
Finally, you can now convert square kilometres into square meters by multiplying by 100:
0.045 x 100 = 4.5 meters
