Answer:

Step-by-step explanation:

If all 70 were nickels, the value would be $3.50 Since that is 2.25 less, that means it needs 45 more 5 cents. Therefore, you would replace 5 of the nickels with dimes. This means there are 25 nickels and 45 dimes.

How you do multiply complex numbers ? Example : (9 - 4i) (8 + 6i)

Andrew [12]

You multiply them just as you would multiply any normal polynomials, except there is a special rule. Since we know that i = √-1, the rule is that i² = -1. So, let's multiply:

$(9-4i)(8+6i) = 72+54i-32i-24i^2$

Let's simplify this:

$72+22i+(-24*-1)$

$72+22i+24 = 96+22i$

Therefore, your answer is 96 + 22i.
