Step-by-step explanation:

Take
as common. Then,

{y: y= -7, -2, 3, 8} is the range of the function.
One and only one line contains both A and B (assuming, that A and B do not overlap)
Okie, so you have 2 polynomials separated by a plus sign. If there were a number in front of the polynomial, you would need to factor, as well as if there was a negative sign. But there is just an addition sign so you just add as you would normally.
5x + 9 + 3x - 2 = 8x +7
I hope this helps :-)

Answer:
DJ = 48
Step-by-step explanation:
The centroid (J) divides the median into parts that have the ratio 2:1.
DJ : JH = 2 : 1
DJ : (DJ +JH) = 2 : (2+1)
DJ : DH = 2 : 3
DJ = (2/3)DH = (2/3)(72)
DJ = 48
