$\sqrt{-4}$ can also be written as 2i
where i = √-1

$\frac{2i}{4-2-3i} = \frac{2i}{2-3i}$

Rationalizing denominator,

$\frac{2i(2+3i)}{(2-3i)(2+3i)} = \frac{4i-6}{4+9} = \frac{4i-6}{13}$

PLEASE I WILL GIVE BRAINLIEST..................don't do it A

Ivahew [28]

Step-by-step explanation:

b.3n/2 = 7/2

6n = 14

n = 2 1/3

c.-x/2 + 6 = -13/4

-x/2 = -37/4

-4x = -74

x = 18 1/2

d.3x/10 = 2/5

15x = 20

x = 1 1/3

e.x/10 = -20/3

3x = -200

x = -66 2/3

f.269x/56 = 10

269x = 560

x = 2 22/269
