Since there is an expression in the square root, it must be non-negative. So:

Then, the interval is:
Step-by-step explanation:
Longest side is between 36 and 18 feet
18 < L < 36
IF longest side were 36 feet, width =0
IF longest side were 18, then width = 18
to be longest L>W L>18. and L can't be as much as 36 to keep width >0
For this question, you would simply plug in a 2 wherever you see an x and plug in a 6 wherever you see a y. Then you simplify the expression.
3(2) + 8(6) - 7
6 + 48 - 7
47
Hope this helps!
Answer:
x = 75
Step-by-step explanation:
20/50 = 30/x
Divide the numbers and find x. If you plug back in 75 for x and simply, you should get the same fraction for each, 4/10.
