Answer: 6

The equation given to you is in the form (x-h)^2 + (y-k)^2 = r^2

The right hand side 36 is in the place of r^2, so r^2 = 36 leading to r = 6 after you apply the square root to both sides.

What is the sum of 12 – 5i and –3 + 4i?<br> –16 + 63i <br>9 – i <br>9 – 9i <br>15 – 9i

Svetach [21]

Answer:

$\boxed{ \bold{ \huge{ \boxed{ \sf{9 - i}}}}}$

Step-by-step explanation:

$\sf{12 - 5i + ( - 3 + 4i)}$

When there is a ( + ) in front of an expression in parentheses, there is no need to change the sign of each term. That means, the expression remains the same. Just remove the parentheses

$\longrightarrow{ \sf{12 - 5i - 3 + 4i}}$

Collect like terms

$\longrightarrow{ \sf{ 12 - 3 - 5i + 4i}}$

Subtract 3 from 12

$\longrightarrow{ \sf{9 - 5i + 4i}}$

Collect like terms

$\longrightarrow{ \sf{9 - i}}$

Hope I helped!

Best regards! :D
