Amirror frame in the shape of an oval is shown below. the ends of the frame form semicircles: an oval is formed by a rectangle with semicircles at each end. the length of the rectangle is 62 inches. the width of the rectangle is 27 inches. which of the following is the perimeter of the inner edge of the frame? (π = 3.14) 146.78 inches 208.78 inches 293.56 inches 347.56 inches

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
