I drew my own picture but my answer got deleted in the meantime because I used a figure from another website.

We have PC = PB + BC = 4 + 12 = 16

PA² = PB·PC = 4(16) = 64

PA = 8

Answer: 8

What is the value of (-7 + 3i) - (2-6i)?
Doss [256]

Answer:

9 (i - 1)

Step-by-step explanation:

Simplify the following:

-7 + 3 i - (-6 i + 2)

-(2 - 6 i) = -2 + 6 i:

6 i - 2 - 7 + 3 i

-2 + 6 i - 7 + 3 i = (6 i + 3 i) + (-2 - 7) = -9 + 9 i:

9 i - 9

Factor 9 out of 9 i - 9 giving 9 (i - 1):

Answer:  9 (i - 1)
