Answer:
13
Step-by-step explanation:
(3-2i)(3+2i) = 9 + 6i - 6i - 4i^2
9 - 4i^2
9 + 4 = 13
Mark and Don have to sell 11 and 59 marbles respectively.
<em><u>Explanation</u></em>
Lets assume, the number of marbles Mark has is 
As, Don has 4 more than 5 times the number of marbles mark has, so the number of marbles Don has 
Question says that the total number of marbles is 70. So, the equation will be...

<em>So, the number of marbles Mark has = 11 </em>
<em>and the number of marbles Don has =
</em>
Hi there! The answer is n = 10.

As you see at the powers of x, we need to add the exponents of the power we when multiply them.

The powers of y work the same way.

Hence, n = 10, since
Answer:
3/1
Step-by-step explanation:
The average rate of change is the distance between y values divided by the distance between x values. We know this as rise/run or slope for linear equations. For non-linear equations, we calculate the average over an interval.
This function has y-values of -1 at x=0 and 5 at x=2.
We add -1+5=6 and divide this by 2-0=2.
6/2=3.
The y-values on average change 3 units for every 1 unit of the x-values.
