Answer: the product is = 33+4i
Step-by-step explanation:
21+4i-12i^2
21+4i-12(-1) i^2=-1
21+4i+12
your answer would be 33+4i .

Step-by-step explanation:
Answer:
5) x = 24
6) x = 48
Step-by-step explanation:
I'd be glad to help :)
For question 5, we know that 62 and the unknown angle is a straight angle, so 62+y = 180. y = 118. We also know all the angles in a triangle add up to 180, so x+(x+14)+118 = 180. Therefore, 2x+132 = 180. We now know that 2x = 48, so x = 24 for question 5.
For question 6, We know that because the line is divided up, (x+35) can be moved down a line, so (2x+1)+(x+35) = 180, so 3x+36 = 180. We now know that x = 48 for question 6
Answer:
Step-by-step explanation:
i think eq. of circle is
x²+y²-2x+4y-18=0
compare with x²+y²+2gx+2fy+c=0
center is (-g,-f) or (1,-2)
radius is √(g²+f²-c)=√((1)²+(-2)²-(-18))
=√(1+4+18)
=√23
