Answer:
<u>x = -7.5 - 1.5(n−1) </u>
Step-by-step explanation:
the explicit formula for the arithmetic sequence has the form
x = a + d(n−1)
a is the first term and d is the common difference
The given arithmetic sequence is
-7.5,-9,-10.5,-12
The first term is -7.5
d = common difference = -9 - (-7.5) = -1.5
∴ x = -7.5 - 1.5(n−1)

we know that
In the right triangle ABC
Applying the Pythagorean Theorem
we have
substitute
Sqrt(80) = Sqrt(16) x sqrt(5)
= 4 x sqrt(5)
Answer:
The least common multiple of 8 and 12 is 24
Explanation:
Find and list the multiples each number until the first common multiple is found.
This is the lowest common multiple .
Multiples of 8
8, 16, <u>24</u>, 32,40
Multiples of 12
12,<u>2</u><u>4</u>, 36,48
Therefore,
LCM of 8 and 12 is 24
