Answer:
Step-by-step explanation:
x^2/100 + y^2/25=1 -----(1)
Since 25<100
Hence the above equation is of the form x^2/a^2+ y^2/b^2=1-------(2)
Comparing (1) and (2)
a^2=100
a=10
Major axis=2a=20

Answer:
33, 11, 24 feet
Step-by-step explanation:
Let s represent the length of the second side. Then the length of the first side is 3s and the length of the third side is s+13. The perimeter is the sum of side lengths:
(3s) +(s) +(s +13) = 68
5s = 55 . . . . . subtract 13
s = 11 . . . . . . . divide by 5
The side lengths are ...
33, 11, 24 feet
