(4+5i)(4-5i)=(4)²-(5i)²=16-25(i)²=16-25(-1)=16+25=41
Answer:
Step-by-step explanation:
The orange divisor(s) above are the prime factors of the number 168. If we put all of it together we have the factors 2 x 2 x 2 x 3 x 7 = 168. It can also be written in exponential form as 23 x 31 x 71

The answer for the first one is (3,2) because both lines pass through this point. :)
Answer:
36 m
Step-by-step explanation:
PT = x
This is True because of similar sides 
solve for x to get PT and you get 16
Then to find the perimeter you would do P = PR + PR + PT = 6m + 14m + 16m = 36m
