Given:
a + bi = 13 + 9i
Equate the real parts:
a = 13
Equate the imaginary parts:
b = 9
Answer:
a =13
b = 9
Answer:
13
Step-by-step explanation:
- x × (x + 9) = x² + 9x = 286
- x² + 9x - 286 = 0
- (x - 13)(x + 22)
- x = 13 or -22
- Since you cannot have negative length, it’s 13
Answer:

Step-by-step explanation:
All you gotta do is subtract - b + c from both sides then simplify.
65*1.60=$104
Hope that helps
