The area of a closet floor 3 yards by 3 yards and each custom tile that makes up the flooring is 1 1/2 square feet. how many tiles are needed to cover the floor?

  54

Explanation:

1 yard = 3 feet. 3 yards = 3 x 3 = 9 feet.

Area of the floor = 9 x 9 = 81 square feet

Total tiles required = 81÷1 1/2

81×2/3=54

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

maya’s expression will generate the wrong sum because she violated the commutative property.
