The answer to this is x=3
Answer:
Correct answer is third from the top an = 27 · (1/3)∧(n-1)
Step-by-step explanation:
Given geometric sequence : 27, 9, 3, 1,....
First term a1= 27, second term a2= 9, third term a3= 3 etc...
Standard form of the n-th term is
an = a1 · q∧(n-1)
We will find quotient when we divide second term with first and third with second
q = a2/a1 = a3/a2 = 9/27 = 3/9 = 1/3
Formula fot n-th term is
an = 27 · (1/3)∧(n-1)
God with you!!!
Answer:
8x² - 14x - 15
Step-by-step explanation:
(4x + 3)(2x - 5)
8x² - 20x + 6x - 15
8x² - 14x - 15
Answer:
- sum: 3x² -4x -4
- product: (x -2)(3x +2)
Step-by-step explanation:
The areas of four regions are given. We can simply add them to find the sum. To express them as a product, we need to look at common factors.
<h3>Sum</h3>
The total of the given area expressions is ...
3x² +2x -6x -4 = 3x² -4x -4 . . . . sum
<h3>Product</h3>
Extending the table to show common factors of each row and column, we have ...

Since each cell of the table is the product of the corresponding common factors, we can write the area as the product ...
(x -2)(3x +2) . . . . product
