63+22i

Step-by-step explanation:

(8-3i) (6+5i)

first: 8*6 = 48

outer: 8*5i = 40i

inner: -3i*6 = -18i

Last: -15i^2 = -15(-1) = 15

Add them together = 48+40i-18i+15

                                = 63+22i

false

step-by-step explanation:

4y - 6 + 4y^2 - 9

before simplifying this contains 4 terms

after simplifying

4y -15 + 4y^2

it contains 3 terms

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.

with the cards, the chance of picking dog is 0.4. having two people pick one is like picking a card twice in a row. so 0.4 * 0.4 is 0.16, or 16%
