Gerardo has 68 baseball cards in his collection. Luke has four times as many baseball cards as Gerardo. Luke buys 25 more baseball cards.
Which equation can be used to find c, the number of baseball cards Luke has in his collection now?
O4 + 68 -25 = 0
4 + 68 + 25= C
4 x 68 + 25 = C
O 4 x 68 - 25 = C

3rd option

Step-by-step explanation:

x =-.20752

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

x = 12

y = 1

for the points!
