Answer:
(5 + 3i)(5 − 3i) = 34
Step-by-step explanation:
The multiplication of two identical binomials who have different symbol, can be solved using the factoring case of a difference of squares:

So, in this case:


Remember that 
So: 
We replace on the polynomial:

<span>To find the slope, you divide the difference of the y-coordinates of a point on a line by the difference of the x-coordinates. It is expressed as:
slope = (y2 - y1) / (x2-x1)
slope = 8-(-7) / 4 - 4
slope = 15 / 0
slope = undefined <------ SECOND OPTION
The line should be vertical where the slope is undefined. Hope this answers the question. Have a nice day.</span>
Answer:
Less than
Step-by-step explanation:
1/4 = 0.25 and 2/3 is approximately 0.67 so 1/4 is less than 2/3
