Answer:
see explanation
Step-by-step explanation:
given 
To rationalise multiply the numerator/denominator by the conjugate of the denominator
the conjugate of 3 + 7i is 3 - 7i, hence
distribute the numerator/denominator
= 
[ note that i² = - 1 ]
= 
= 
= 
+ 
i
= 
+ 
i ← in standard form
Is this the original question or?

Hope this helps!
Multiply by 4 is your rule
3 x 4 = 12
6 x 4 = 24
12 x 4 = 48
To solve for the answer for 24, multiply it by 4
24 x 4 = 96
96 is the match for 24
hope this helps
Answer:
C
Step-by-step explanation:
For the given intervals
( - ∞, - 5) ← use any value < - 5 but not - 5, the parenthesis ) indicates that x is less than - 5 but not equal to - 5
(- 5, - 1) ← - 4, - 3, - 2 can be used but not - 5 or - 1
(- 1, 4) ← 0, 1, 2, 3 can be used but not - 1 or 4
(4, ∞ ) ← use any value > 4 but not 4
Hence
3 can be used in (- 1, 4)
- 6 can be used in (- ∞, - 5)
zero can be used in (- 1, 4)
- 5 cannot be used in any of the given intervals
