Put it in the form

ax^2 + bx + c = 0

use the quadratic formula

x = [ -b + sqrt( b^2 - 4 ac ) ] / 2a

x = [ -b - sqrt( b^2 - 4 ac ) ] / 2a

7v^2 - 7v - 22 = 0

a = 7
b = -7
c = -22

v = [ 7 + sqrt ( 49 - 4 * 7 ( -22) ] / 2 * 7 = 2.34

v = [ 7 - sqrt ( 49 - 4 * 7 ( -22) ] / 2 * 7 = -1.34

The heaviest freshwater fish caught in region A weighs 209 lb, and the heaviest freshwater fish caught in region B weighs 629 l

Colt1911 [192]

Answer:

$Region\ A= \frac{209}{2240}\\\\Region\ B= \frac{629}{2240}$

Step-by-step explanation:

The English ton, also known as the long ton, is equivalent to 2,240 pounds. Therefore, the fractional parts, of each of the two fish, of the English ton are:

Fish caught in region A:

$A= \frac{209}{2240}$

Fish caught in region B:

$B= \frac{629}{2240}$

Both fractions are irreducible.
