Set up a system of equations.
l=4w
2l+2w=110
Substitute l in to the second equation.
2(4w)+2w=110
8w+2w=110
10w=110
w=11
Substitute w back into the first equation.
l=4(11)=44
So, the length is 44 feet and the width is 11 feet.

729 is 3 to the 5th power
3 x 3 x 3 x 3 x 3 is 729
x^2 + 6x + 7 = (x + 3)^2 - 2
So the axis of symmetry is x = -3
