Answer:
90
Step-by-step explanation:
45/3 = 15
15/3 = 5
5/5 = 1
45 = 3^3 * 5
30/2 = 15
15/3 = 5
5/5 = 1
30 = 2 * 3 * 5
To find the LCM, you need the product of the factors that are common and not common with greater exponent.
2 is not common. Use it.
3 is plain 3 in 30 but 3^2 in 45, so use 3^2.
5 is common, so use 5.
LCM = 2 * 3^2 * 5 = 90
I believe the answer would be c

Step-by-step explanation:
Answer: This is a linear equation. The graph is a diagonal line with a slope of +1. The y-intercept is -1
Step-by-step explanation: The line intersects the y-axis at -1 and the x-axis at +1
Answer:
a_n = n^2 − 1
Step-by-step explanation:
The numbers can be described as a polynomial with the following formula:
a1 = 1^2 − 1 = 1 - 1 = 0
a2 = 2^2 − 1 = 4 - 1 = 3
a3 = 3^2 − 1 = 9 - 1 = 8
a4 = 4^2 − 1 = 16 - 1 = 15
a5 = 5^2 − 1 = 25 - 1 = 24
