For a party, Svetlana brought 4 packages of cookies with 16 cookies in each package. She and her friends ate all but 6 cookies,
Which equation can be used to find C, the total number of cookies they ate?
O A, C = (4x 16) + 6
OB, C = (4 + 16) - 6
OC, C = (6 x 16) - 4
OD. C = (4x 16) - 6
O E C = (6 + 16) + 4

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
