The flower garden has the shape of a right triangle. 51 ft of a perennial border forms the hypotenuse of the triangle, and one leg is 21 ft longer than other leg. find the lengths of the legs. a right triangle has a vertical side of unlabeled length, a horizontal side of length x, and a hypotenuse of length 51 feet.

Let
x------> larger leg
y------> smaller leg

we now that
x=y+21----> equation 1
51²=x²+y²----> equation 2
substitute 1 in 2

2601=[y+21]²+y²----> 2601=y²+42y+441+y²
2y²+42y-2160=0

using a graph tool----> to resolve the second order equation
see the attached figure

the solution is 
y=24 ft
x=y+21-----> x=24+21-----> x=45 ft

the answer is
The length of the larger leg is 45 f
The length of the smaller leg is 24 ft

At a constant it will take one hour to travel 32 mi.at that speed it will take 1/2 hr to travel the remaining 16 mi.it will take 1+1/2 hr to travel the 48mi @ 32mph.so 1 hr = 60 min& 1/2 hr = 30 min1+1/2 hr = 90 min.there are 60s in each 90 × 60 = 3600 seconds.the real question seriously is he why are they driving so slow? ! lol.
