AB=707
Step-by-step explanation:
D is correct:
because of doing the correct steps:
step1: put the point of your compass on the left endpoint of the segment, A.
Open the compass to be more than half the length of the segment. Then leave a half-circle mark.
step2: do the same thing on the other point B. and find the middle point.
[tex]15000= \frac{5}{7}*x[\tex]
[tex]x=15000* \frac{7}{5}=21,000[\tex]
Check 21,000 * 2/7 = 6.000 and 6,000 + 15,000 = 21,000
Answer:
9 units
Step-by-step explanation:
Distance, not difference. :)
Because these two points have the same x-coordinate, 0, the line segment connecting them is part of a vertical line. To find the disance between these points, we merely subtract the y-coordinates: 12 - 3 = 9.
That distance is 9 units.
