Answer:
a, c, d, f for sure has a hypotenuse but id-k if e would count
Step-by-step explanation:
In an observational study, only one group is studied, and in an expirement, two groups are studied.
Perimeter (p) = 2×length (l) + 2×width (w)
p = 2l+2w
area (a) = l×w, so solve for one (I'll use l):

since p = 30, and a = 50, substitute the "a÷w" in for l in the perimeter equation:

Now plug in p and a values:


therefore width can be either 5 or 10 (but not both), so let's plug in:
l = a÷w = 50÷5 = 10
So if w = 5, then l = 10
D) 5 feet, and 10 feet
Answer:
Your answer is: A) True
( I say true because 1) .5 2) 7 are rational) ( I dont know about v16, if that is what it is supposed to say, then I cant quite tell)
A rational number is any integer, fraction, terminating decimal, or repeating decimal.
