While watching a football game, lin chow decided to list yardage
gained as positive integers and yardage lost as negative integers. after
these plays, lin recorded 14, –7, and 9. what was the net gain or loss?

The answer should be 16 because they gained 14 yards, then they lost 7 yards, and finally they gained 9 yards.

14 -7 + 9 = 16

simplifying

7ln(x + 2.8) = 11.2

reorder the terms:

7ln(2.8 + x) = 11.2

(2.8 * 7ln + x * 7ln) = 11.2

(19.6ln + 7lnx) = 11.2

solving

19.6ln + 7lnx = 11.2

solving for variable 'l'.

move all terms containing l to the left, all other terms to the right.

reorder the terms:

-11.2 + 19.6ln + 7lnx = 11.2 + -11.2

combine like terms: 11.2 + -11.2 = 0.0

-11.2 + 19.6ln + 7lnx = 0.0

the solution to this equation could not be determined.

step-by-step explanation:

i searched it on google but it says that the solution to this equation could not be determined but i hope that it you a little.
