Match each product of complex numbers with its value.
pairs -6, 5 , 7 , -2
complex numbers i^2(2i^2-5) , i^2(3+ i^2) , 2i(2i- i^3) , i(4i^3-i)

Distributive property says that:

We know that

where i is the imaginary

Given the complex numbers:

A.

⇒

B.

⇒

C.

Using distributive property

⇒

⇒

D.

Using distributive property

⇒

⇒

⇒

Therefore. matching defined as:

A.  → 7

B.  → -2

C.  → -6

D.    →  5

the inequality is:

250c+180g≥950

step-by-step explanation:

let c denotes the number of days in a week   miyoko worked as a cryptographer.

and g denotes the number of days in a week she works as a geologist.

now we are given that she earns $250 for every day she works as a cryptographer,and earns $180 for every day she works as a geologist.

now miyoko's goal is to earn more than $950 this week.

hence, the inequality could be represented as:

250c+180g≥950
