L=W+10
area= LW=375
375=W(W+10)
w^2+10W-375=0
completing the square
W^2+10w+25=400
(w+5)=20
w=15,L=25
area= LW=375
375=W(W+10)
w^2+10W-375=0
completing the square
W^2+10w+25=400
(w+5)=20
w=15,L=25
width --- x ft
length -- x+10 ft
solve
x(x+10) = 375
x^2 + 10x - 375 = 0
(x+25)(x-15) = 0
x = 15 or x = a negative
width: 15 ft
length : 25 ft
check: 15x25 = 375
length -- x+10 ft
solve
x(x+10) = 375
x^2 + 10x - 375 = 0
(x+25)(x-15) = 0
x = 15 or x = a negative
width: 15 ft
length : 25 ft
check: 15x25 = 375
