I think it should be 31.5
6 builders over 21 days would be equal to 9 builders over X days. Then you would cross multiply
3/5 > 1/2 ~ because 3/5 is 60% of 1 and 1/2 is 50% of 1
2/6<1/2 ~ because 2/6 is 33% of 1 and 1/2 is 50% of 1
Hope I helped!

0≤h(t)≤144, which means that the height of the object can be between 0 and 144 feet, including those limits.
XY = −1−(−10) = 9
(line x = −5) = −5−(−9) = 4
Area = 1/2 * 9 * 4 = 18
Answer:
M
Step-by-step explanation:
AB was dilated by scale factor of 2 to create A'B'.
Connect points A and A' with a straight line, connect points B and B' with a straight line. The point where these two straight lines will intersect is the center of dilation.
As you can see, these lines intersect at point M, so, point M is the center of dilation.
