Perimeter of a triangle with side lengths 2x, (3x-1) and (4x+5)?

Does is have a total perimeter of the triangle? If not, the closest you can get is by simplifying.

2x+3x-1+4x+5

9x+4

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)
