Question

the flower garden has the shape of a right angle. 17ft of perennial border forms the hypotenuse, and one leg is 7ft longer than the other leg, find the lengths of each leg (diagram to follow)

Answer 1

solve
\[x^2+(x+7)^2=17^2\]

Answer 2

ahhh i see, i was having trouble on the way the equation should be written

Answer 3

\[x^2+x^2+14x+49=289\]
\[2x^2+14x-240=0\]
\[x^2+7x-120=0\]
\[(x-8)(x+15)=0\]
\[x=8\]
