Find the number of real number solutions for the equation.
x2- 6=0

x=3

Step-by-step explanation:

2x-6=0

2x=0+6

2x=6

2x/2=6/2

x=3

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)

$12. that is my answer.
