Lelechka [254]

Answer:

$\boxed{7-26i}$

Step-by-step explanation:

The binomials are multiplied in the usual way, using FOIL or the distributive property:

(5 -2i)(3 -4i) = 15 -20i -6i +8i²

Since i² = -1, this becomes ...

= 15 -20i -6i -8 = 7 -26i

Charlie's weight is nine kilograms greater than his brother's. Together they weigh 99 kilograms. Let x represent the weight of t

siniylev [52]

If the weight of the little brother is x, then the weight of Charles is x + 9

The equation that can be used to determine what each one weighs is:

x + (x + 9) = 99.

Let us now solve it.

x + x +9 = 99

2x + 9 = 99

2x = 99 - 9

2x = 90

x = 90/2

x = 45

Little brother's weight is 45 kg.

Charles' weight will be 45 + 9 = 54 kg

Adding these two weights will give 99kg
