Bill has a box of markers that has a base of 8 cm x 20 cm wide and they height of 6 cm. martins pencil box hasn't had a 4 cm and a base of 15 cm x 16 cm. bill says marker box has the same volume as martins pencil box is bill right? explain.

make sure you have version 2.50

try looking in the very back of the book : )

step-by-step explanation:

4^(x+2)=12

4^(x+2)=12

take the log base 4 on each side

log 4 (4^(x+2) = log 4(12)

we know log b(a^y) = y log b (a)

(x+2) log 4(4) = log 4 (12)

x+2 = log 4 (12)

we know   logb c = loga c/loga b

we want to convert to base 10   so a = 10

by default, we do not write the 10   c = 4   and b = 10

log4 10 = log 12/log 4

log4 10 = log 12/ log 4

x+2 = log 12/ log 4

subtract 2 from each side

x +2 -2 = log 12/ log 4 -2

x = 1.79248125 -2

x =-.20752
