Factor the polynomial: x(5x - 8) - 2(5x-8) O A. 2x(5x-8)
оо
O B. (5x-8)(x+2)
C. (5x-8)(x - 2)
D. -2x(5x-8)

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)

it is x equals 3   plese mark me really need it
