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
Answer:
See below
Step-by-step explanation:
Area of a circle = pi * r^2
for this circle : Area = 3.142 * 10 * 10 = 314.2 cm^2
Answer:
L = P/2 - W, or L = (P - 2W)/2
Step-by-step explanation:
If P = 2L + 2W, dividing all terms by 2 yields P/2 = L + W. Then:
L = P/2 - W, or L = (P - 2W)/2
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!
