Question 57976: 60. Rectangular stage. One side of a rectangular stage is 2 meters longer than the other. If the diagonal is 10 meters, when what are the lengths of the sides.
X + 2m
Let x be the length of one side.Therefore the other side's length is x+2. Given diagonal=10m.Therefore
10^2=x^2+(x+2)^2
100=2x^2+4x+4
2x^2+4x-96=0
x^2+2x-48=0
(x-6)(x+8)=0
x-6=0,x+8=0
x=6,x=-8
x=-8 is absurd.Therefore x=6
hence the lengths are 6m & 8m

Question 57978: Please help me. I do part of the equation and then I am just lost.
A rectangular garden is to be surrounded by a walkway of constant width. The garden's dimensions are 30 ft by 40 ft. The total area, garden plus walkway, is to be 1800 ft2. What must be the width of the walkway to the nearest thousandth?
I have done
(40+2x)(30+2x)=1800ft^2
1200+80x+60x+4x^2=1800ft^2
4x^2+140x-1284 = 0(Ugh)
2x^2+70x-642=0
x=-70+/-sqrt70^2-4(2)(642)/2(2)
Am I right so far? Now I don't understand what comes next.
