A watercolor painting is 16 inches long by 12 inches wide. Ramon makes a border around the watercolor
painting by making a mat that adds 2 inches to each side of the length and the width. What is the area of
the mat?

252in. squared

Step-by-step explanation:

16+2=18

12+2=14

14×18=252 ^2

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)
