Solve the following equation: 3x^2=-12
A. X=2
B. x=-2
C. No real solution
D. X= +2

I think that it's +2, but seeing as I don't know what type of formula you need (several ways depending on what you are learning, solving for x, solving quadratic, etc?)

Step-by-step explanation:

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)

if the pizza is divided equally into 2 equal halves then you would get

πr^2/2

where r is the radius of the pizza.
