Answer:
Sum = 13+ 4i Difference = -5 - 8i
Step-by-step explanation:
Given complex number as (4 -2i) and (9 + 6i)
Sum of these complex number is
(4 -2i) + (9 + 6i) = ( 4 +9) + (6i -2i)
= 13 +4i
Difference of these complex number is
(4 -2i) - (9 + 6i) = (4 -9) - (2i +6i)
= -5 - 8i
Hence the sum and Difference of given complex numbers are
Sum = 13+ 4i Difference = -5 - 8i Answer
Given:
The equation
goes through the coordinates (6,5) and (-2,-5).
To find:
The values of A and B.
Solution:
We have,

It goes through the coordinates (6,5) and (-2,-5). It means these points will satisfy the equation.

...(i)

...(ii)
Adding (i) and (ii), we get


Divide both sides by 4.

Put A=5 in (i), we get
Divide both sides by 5.

Therefore, the values of A and B are 5 and -4 respectively.

C and E are the right ones
Some triangles can have a right angle, but not all triangles are right angles. If a triangle has a right angle, it has one angle of 90°. Triangles have a total of 180°.
