Steps would be as follows:
1- Read the problem carefully
2- Identify what you are trying to find
3- Make a plan
4- Solve the problem
5- Check that your answer makes sense
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)
Answer:
I think A and C
Step-by-step explanation:
Im srry if its wrong, but my older sister says that its A and C
A² + b² = c²
a² = c² - b²
a² = 9² - 6²
a² = 81 - 36
a² = 45
a = √45
a ≈ 6.7082
a = 6.7
