Step-by-step explanation:
15,729 = 10 000 + 5 000 + 700 + 20 + 9
= (1 x 10000) + (5 x 1000) + (7 x 100) + (2 x 10) + (9 x 1)
We can also write it like this :
(1 x 10⁴) + (5 x 10³) + (7 x 10²) + (2 x 10¹) + (9 x 10⁰)
Step-by-step explanation:

The answer is C. AB. The total line segment is ACB, or AB, because C is in between A and B. If you are adding AC and CB together, you are adding the two parts of the line together.
I hope this helps :)
When you factor this problem you get:
(3x+5)(x+10)
0 because when x is 6 y is on the bottom of the x axis or at 0
