scoundrel [369]
L=2w+6
260=lw

Substitute for l
260=w(2w+6)
260= 2w^2+6w
2w^2+6w-260=0
2(w^2+3w-130)
2(w+13)(w-10)
w=-13, w=10

Since width cannot be negative it must be 10
260=l(10)
26=l

Final answer: length-26 ft, width-10ft

Mr. Lopez asked kids from after school what there favorite dessert is. 15% voted for cinnamon twirls and 85% voted for jumbo coo
mafiozo [28]
85/15 is 5 2/3

so, to find 85% with 15%, you would multiply 12 (also 15%) by 5 2/3.

12*5 2/3=68.

you could also find it using the 1% method:

1% of 15 is .15.
.15*85=68.

Hope this helps!
