Plz help me I dont understand The question is Select all the true statements if -8x - 8 + 8x - 8 is simplified
A. - 8 and - 8 are constants and also like terms. They can be added.
B.-8x +8x are like terms and they can be added. And the result is -16x2
C. -8x -8 +8x -8 = -16
D. -8x -8 +8x -8 = -16x
-8x -8 +8x -8 = -32x

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)

they disappear if your absent from to long. i found out that the hard way.
