Answer:

B

Step-by-step explanation:

We have the expression:

[tex](3-5i)(-2+4i)[/tex]

Distributive Property:

[tex]=(3-5i)(-2)+(3-5i)(4i)[/tex]

Distribute:

[tex]=(-6+10i)+(12i-20i^2)[/tex]

Simplify:

[tex]=(-6+10i)+(12i-20(-1))[/tex]

Simplify:

[tex]=-6+10i+12i+20[/tex]

Combine like terms:

[tex]=(-6+20)+(10i+12i)[/tex]

Simplify:

[tex]=14+22i[/tex]

Hence, our answer is B.
