Answer:

16x³ + 9x² + 9x + 13

Step-by-step explanation:

Given

6x³ + 8x² - 2x + 4 and 10x³ + x² + 11x + 9

Sum the 2 expressions by adding like terms, that is

= (6x³ + 10x³) + (8x² + x²) + (- 2x + 11x) + (4 + 9)

= 16x³ + 9x² + 9x + 13

How do i find the circumcenter of a triangle with an undefined slope
gulaghasi [49]

The slope perpendicular to an undefined slope is: 0

Example:

x = 5 is a vertical line and has an undefined slope.

The line perpendicular to it is y = <em>any value</em> which has a slope of 0.


I hope this makes sense.  If not, please post the homework question so we can help you find the circumcenter.

Please show work on how you got the answer
Maurinko [17]
Since E is the midpoint, DE and EF are the same length.
Set the equation DE and EF equal to each other and solve for x.
2x + 4 = 3x - 1
x = 5
Then plug in 5 to find the length.
DE = 2(5) + 4 = 14
EF = 3(5) - 1 = 14
DF = DE + EF = 28
