What's (8 + 3i)(3 + 5i).

1 answer:

7 0

Hello there!

(8 + 3i)(3 + 5i)

We must distribute each number/variable to the others in the opposite parenthesis.

8(3 + 5i) = 24 + 40i
3i(3 + 5i) = 9i + 15 $i^{2}$

Combine like-terms.
40i + 9i = 49i.

Now, put your simplified answer in Standard Form;
15 $i^{2}$ + 49i + 24

This is your answer.

I hope this helps!

8) 7(p-6)= 8p - 34 any chance i can get the steps on how to solve this?

yan [13]

Answer:

Step-by-step explanation:

7(p-6)=8p-34

Distribute 7 into the parentheses on the Left Hand Side of the equation

7p-42=8p-34

get p together, so minus 7p on both sides

7p-7p-42=8p-7p-34

7p and -7p cancel out on L.H.S

-42=p-34

isolate p by adding 34 to both sides

-42+34=p-34+34

-34 and postitive 34 cancel out on the R.H.S

p=-8

Hope this helps! :)

PLEASE HELP ITS URGENT how can you use an equation to make a prediction from a pattern?

allochka39001 [22]

An equation can be used to predict values from a pattern by merely substituting any value to determine the equivalent value. An example is the geometric series which has a standard equation of an = a1 * r^(n-1) and is used to predict the nth term of the series
