Answer:
30
Step-by-step explanation:
The factors of 120 are: 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, <u>30</u>, 40, 60, 120
The factors of 150 are: 1, 2, 3, 5, 6, 10, 15, 25, <u>30</u>, 50, 75, 150
Then the greatest common factor is 30.
Answer: 23.29
yes, ±2
The x-intercepts are found by setting y=0 and solving for x:
x^2/4 = 1
x^2 = 4
x = ±√4
x = ±2
The x-values of interest are -2 and +2.
well you should firstcalculate the distance then divide by the primary source and you should be able to get the answer after substituting
