Answer:
4). 47 - 29i
Step-by-step explanation:
(5+√-36)*(1-√-49)=5*1 -5√-49+1*√-36 -√-36√-49 = 5-5*7i +6i-6i*7i=
=5-35i+6i-42(-1)=5+42-41i= 47 - 29i
Answer:
Yes, SAS theorem. Angle ACB and Angle ECD are congruent because of the vertical angles theorem.
Step-by-step explanation:
7X-4=6X-4-X
7X-6X+X=0
2X=0
X=0
The solution for your answer is 12
So i think here you would FOIL. so -5x^2+10x-5x+10 and then combine like terms :)
