Answer:
I think 1, 4, 5 and 7
Step-by-step explanation:
As given
![A = \frac{1}{2} * b* h](https://tex.z-dn.net/?f=A%20%3D%20%20%5Cfrac%7B1%7D%7B2%7D%20%2A%20b%2A%20h%20)
Firstly we will multiply both sides by 2.
![2*A = 2* \frac{1}{2} * b * h](https://tex.z-dn.net/?f=2%2AA%20%3D%202%2A%20%20%5Cfrac%7B1%7D%7B2%7D%20%2A%20b%20%2A%20h%20)
![2A = bh](https://tex.z-dn.net/?f=2A%20%3D%20bh)
Now dividing both sides of equation from h.
![\frac{2A}{h} = \frac{bh}{h}](https://tex.z-dn.net/?f=%20%5Cfrac%7B2A%7D%7Bh%7D%20%3D%20%20%5Cfrac%7Bbh%7D%7Bh%7D%20%20)
![\frac{2A}{h} = b](https://tex.z-dn.net/?f=%20%5Cfrac%7B2A%7D%7Bh%7D%20%3D%20b%20)
So b =
Answer:
A. neither; 7, -20, 61
Step-by-step explanation:
The given terms do not have a common difference, so the sequence is not arithmetic.
The given terms do not have a common ratio, so the sequence is not geometric. (Any sequence with 0 as a term cannot be geometric.)
The sequence is <em>neither</em> arithmetic or geometric.
___
The first differences of the terms of this sequence are ...
-1, 1, -3
If we choose answer A (the only selection with "neither"), it suggests the next 3 terms are 7, -20, 61. These terms make the next differences be 9, -27, and 81. After the first term, the differences of the proposed sequence have a common ratio of -3. However, the first term needs to be 1/3 in order for that rule to be consistent for the whole sequence.
9(4r-6) it is in factor form.
