PLEASE ASNWER ASASP FOR BRAINLEST

I got 36.

Step-by-step explanation:

You first multiply 12x7 which is 84, and since it is a triangle, you divide by 2. You then have 42. After this, you multiply the hole 2x3 and you get 6. You then subtract 6 from 42 and you get 36.

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)

the answer is 1 becuz if it were 1.0 that would rip apart the entire so ya. : )
