Answer:
option 1
Step-by-step explanation:
It's given in the question that
a (first term of an A.P.) = 14
d (common difference between terms of A.P.) = -3
So,
2nd term will be = a + d = 14 + (-3) = 11
3rd term = a + 2d = 14 + 2×(-3) = 8
4th term = a + 3d = 14 + 3×(-3) = 5
All these terms are matching with option 1. So, option 1 is the correct option
1.5625 is the answer

Step-by-step explanation:
<u>Step 1: Define</u>
7s² + 9 + -2s²
<u>Step 2: Simplify</u>
- Rewrite: 7s² + 9 - 2s²
- Combine like terms (s²): 5s² + 9
So a perfect square trinomial like
has its middle term, by multiplying 2 * the left guy * the right guy
so.. .let's see your equation now x² - 3x +n
so.. the middle term is 3x, neverminding the sign
It is 17.86 percent I just rounded it but it was originally 17.8571429%
