<em>Variables, televisions, generic version, TV brand, dimensions </em>
For this case we have two televisions, one generic version and one brand. We know that the generic version represents the size of the brand. We must define two variables that represent the dimensions of the brand TV, so we have:
- x: Brand TV length
- y: Brand TV width
Dimensions of the generic TV:
So:
By clearing the variables we have:
Thus, the dimensions of the brand TV are 18 inches by 36 inches
Answer:
The dimensions of the brand TV are 18 inches by 36 inches
Answer:
<em>summation of five times negative three to the power of n from n equals zero to infinity</em>
Step-by-step explanation:
<u>Summation Notation </u>
It represents the sum of a finite or infinite number of terms. Let's analyze the terms of the given succession:
5-15+45-135+...
If we take 5 as a common factor, we have
5(1-3+9-27+...)
The parentheses contain the alternate sum/subtraction of powers of 3. The odd terms are positive, the even terms are negative, thus the exponent must be n starting from 0 or n-1 starting from 1
The summation is then represented by
This corresponds with the option:
<u>summation of five times negative three to the power of n from n equals zero to infinity</u>
