(-3 - 5i )(-3 + 5i ) = -16 34 34 - 30

Answers

You can use:

(a-b)(a+b)=a^2-b^2

We know:

i=√(-1)\to i^2=-1

Calculate:

(-3-5i)(-3+5i)=(-3)^2-(5i)^2=9-25i^2=9-25(-1)=9+25=34

Answer:

(-3 - 5i )(-3 + 5i ) = 34 , I'm pretty sure 34 is the answer.

Determine whether the given point lies on the graph of the inequality. (-1,-3); -x-6y < 19.

in this case, is the point on the graph (yes or no)

Answers

-x - 6y < 19. 

Point ( -1, -3)   ⇔    x = -1   ,  y = -3
instead of the variables you need to put the values ​​of x and y ( coordinates of the point )
- (-1) - 6*(-3) < 19

we calculate

1 + 18 < 19    record turns mushy

Proposal
the point does not belong to the graph
