Answer:
The coordinates of the fourth vertex of the rectangle is 
Step-by-step explanation:
Let

using a graphing tool
Plot the vertices of the rectangle
The coordinates of point D will be the intersection point of the line parallel to AC that passes through the point B with the line parallel to AB that passes through the point C
The intersection point is 
see the attached figure
Wen you write in standard form, that means you're writing it in number form. For example, instead of writing "eighty-two", you'll write "82". ;-)
Answer:
The roots (zeroes) are -1 and 527 over 3.
Step-by-step explanation:
First, you gotta do the FOIL method and multiply the values which gives u 6x^(2) -1048x - 1054. Then you find the zeroes ( the points in which the the graph intersects with the x-axis). Finally, you set y equal to zero and find the x.
