(2x-3)(4x+1)
(2x+3)(4x-1)
(2x+1)(4x-3)
(2x-1)(4x+3)

whats the image?

Step-by-step explanation:

A)

=

=

B) (Im just being lazy - ^2 = the small )

= 8x^2-2x+12x-3

= 8x^2+10x-3

C)

= 8x^2-6x+4x-3

= 8x^2-2x-3

D)

= 8x^2+6x-4x-3

= 8x^2+2x-3

These are the solutions to it

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)
