2. Jason keeps his dog in a square pen that measures 8 feet on each side. He wants to increase the
length of the pen by x feet, so that the new area of the pen is 116 square feet. Write an equation

step-by-step explanation:

the original amount doesn't ''re just looking for the time it takes for 1/2 of the substance to we have

(1/2) =)     take the ln   of both sides

ln (1/2)   = )   and we can write

ln(1/2) = ) lne     and lne   = 1     so we have

ln(1/2) = -.1092t     divide both sides by -.1092

t = ln(1/2)/-.1092 = about 6.347 days = about 6.3 days (rounded)

21/58.

hope to be marked brainliest

1/800 is the right answer
