What is the quotient of complex numbers below? i needme

4+i

Step-by-step explanation:

13-i

3-i

Multiply by the complex conjugate on the top and bottom

3+i

3+i

13-i           3+i

*

3-i             3+i

FOIL

13*3 +13i -3i - i^2

3*3 +3i  -3i -i^2

39 +10i  -  -1

9 +1

40 +10i

10

Divide the top and bottom by 10

4 + i

step-by-step explanation:

given that there are two triangles j'k'l' and jkl>

the former is got by dilating the second one.

when drawn on a grid, (graph paper) coordinates of vertices of first triangle is

(6,12)j, (9,6)k and (12,9)l

side jk has length = distance between j and k

=

side j'k'=distance between j' and k'

=

ie j'k'l' has sides 1/3 of that of corresponding sides of jkl.

hence scale factor of 1/3 is used to get j'k'l'from jkl
