7×65 7×(60+5)
(7×60) (7×5)
(420)+(35)
The answer is 455
Answer:

And replacing we got:

And then the final term would be:

Step-by-step explanation:
For this case we have the following expression:

And we can use the binomial theorem given by:

And for this case we want to find the fourth term and using the formula we have:

And replacing we got:

And then the final term would be:

Given:
Point is T(-3,8).
To find:
The coordinates of T' after
.
Solution:
We know that,
means the figure reflected across the x-axis then reflected across y-axis.
If a figure reflected across x-axis, then


If a figure reflected across y-axis, then



Therefore, the required point is T'(3,-8).
