First find the total area of the building.
44ft x 74ft = 3256ft^2
Next, since you have 24 tiles per box, each covering 1ft^2 of space, find the number of boxes you need to supply the minimum number of tiles needed to fill the area.
3256ft^2 ÷ 24 = 135.6 boxes
Since you are finding the minimum number of boxes to completely fill the given area, round up.
Answer = 136 boxes
Answer: A (1)
Explanation:
a(11) means column 1, row 1. Therefore, the answer would be the top left value.
Answer:
2827.43
Step-by-step explanation:
First join the log4 on the left:
log4( x*(x-3) = log4(-7x+21)
Then x = -7, works: -7*(-10)=70 = -7*(-7)+21
x=-3, 18 = 42, does not work
x=3 0=0 works,
However, when one puts x = -7 in the *original* exression, log4(-7) or log4(-10) do not exist (you know why?). So x= -7 is extraneous.
Now x=3 gives log4(0) on the left and right, which does not exist.
So, C is the answer, both are extraneous. Seem to work but indeed don't work in the *original* equation
