Answer:
B) 22
Step-by-step explanation:
AC = BD
6x+10 = 10x+2
simplify:
subtract 6x and 2 from both sides:
4x = 8
x = 2
then:
AC = 6(2)+10 = 22
Answer:
-4.3 degrees
Step-by-step explanation:
if I understand the problem correctly, then the temperature at midnight fell 15.7 degrees from 11.4 degrees at noon.
11.4 - 15.7 = -4.3 degrees

Photographing stars requires you to keep your exposure open for a long time. Taking pictures of star trails would take about 30 minutes to three hours. If you multiply that for the 6 stars stated above in the problem then you would be needing that much time if the stars were close and approximately 3 to 18 hours capture their star trails if they were far apart from each other.
The relationship is that the volume of a cube is equal to one edge length cubed or edge×edge×edge
