W=l-8
a=9
a=lw
9=(l-8)l
9=l²-8l
0=l²-8l-9
factor
0=(l-9)(l+1)
set to zero
l-9=0
l=9
l+1=0
l=-1, false length can't be negative
l=9
the length is 9 units long
Answer:
First, you get both of them with same denominator:
3/7 and 2/3 => 9/21 and 14/21, however, there are only 4 rational numbers between 9/21 and 14/21.
The solution is that you can raise the denominator 2 times:
9/21 and 14/21 => 18/42 and 28/42
Now you can select : 19/42, 20/42, 21/42, 22/42, 23/42. They are a group of 5 rational numbers you are looking for.
Answer:
One answer is x = 1, y = -1, and z = 2.
It seems that you have missed the relevant options for your question, but hope these answers can help you find the one. Anyway, the ratio that can be equal to 5/6 is 10/12. Or it can be the following: 15/18, 20/24 or 25/30.
The ratio that is not equal to 4/9 among the given choices which are <span>45/95, 16/36, 8/18, 20/45 is 45/95. The answer is the first option. Since 45/95 is 9/19. Hope these answers help.</span>
