Answer:
Step-by-step explanation:
If the number is 6 then
Product of 8 x 6 = 48
48 - 10 = 38
So the number is 6
Midpoint formula: (x1 + x2)/2 , (y1 + y2)/2
Midpoint AB = (3 +-5)/2, (3 + 7)/2 = -2/2 , 10/2 = (-1,5)
Midpoint CD = (2 +9)/2, (11 + -2)/2 = (11/2,9/2)
Answer:

Step-by-step explanation:
To solve by factoring, complete the square by dividing 8 from 8x in 2. Then square the result 4 to get 16. Add 16 to both sides.

The equation is now factored. To solve, take the square root of both sides and solve for x.
