Answer:
See below.
Step-by-step explanation:
Convert to fractions with a denominator of 4:
2pi + pi/4
= 8pi/4 + pi/4
= 9pi/4.
12,000 pounds, 1 ton = 2000 pounds
(x+4)(x+4+1) = (x+1)(x+1+11)
(x+4)(x+5) = (x+1)(x+12)
x^2 + 4x+5x+20=x^2+x+12x+12
9x + 20 = 13x + 12
13x-9x = 20-12
4x = 8
x = 2
Divide both by 18.
<span>140/18=7.78 </span>
<span>So... $7.78 per foot</span>
