This is the formula you would use to calculate how many tiles you would need.
# of tiles you need = Total square footage ÷ square footage of each tile
Total square footage: 69x69 = 4761 square feet
Square footage of each tile = 2x2 = 4 square feet
# of tiles you need = 4761 ÷ 4 = 1190.25
You will need 1190.25 tiles.
The answer is A because 5 x 3/8 and 15 x 1/8 both equal 15/8.

Answer:
C: 6
Step-by-step explanation:
Let's work backward. If that ? is replaced by 6, we have:
x^2 + 12x + 36 = (x + 6)^2.
The coefficient in question is 6.
