Answer:
42 inches
Step-by-step explanation:
Im guessing that the the table looks like this:
Width Length
3 7
6 14
9 21
So we can see the numbers on the right are increasing by 3 and the numbers on the left are increasing by 7.
The width is 3 times some number, and the length is 7 times the same number.
So if the width was 18 then we know the number would be 3 because 3 * 6 = 18
If that number is 6, then the length will be 6 * 7 = 42
So the length is 42 inches
Hello!
log₃(x) + log₃(x - 6) = log₃(7) <=>
<=> log₃(x * (x - 6)) = log₃(7) <=>
<=> log₃(x² - 6x) = log₃(7) <=>
<=> x² - 6x = 7 <=>
<=> x² - 6x - 7 = 0 <=>
<=> x² + x - 7x - 7 = 0 <=>
<=> x * (x + 1) - 7 * (x + 1) = 0 <=>
<=> (x + 1) * (x - 7) = 0 <=>
<=> x + 1 = 0 and x - 7 = 0 <=>
<=> x = -1 and x = 7, x ∈ { 6; +∞ } <=>
<=> x = 7
Good luck! :)
