OK so I added all them n umber's up from top to bottom up from left to right and I got 42. So sense each tile is 2 bucks, 42*2=84
$17 is the final answer.
explanation: If you times $1.28 By 12.99 your answer is $16.63 and if you round it up to 2 decimal places it's $17 as $16 and 63 cent is closer to $17 than $16
Z^2 - 3z - 18 =
(z + 3)(z - 6)
Okay so in order to find the circumference we would first need to find either the diameter or radius of the circle. The perimeter of the square is 40 and each side is equal. 40/4 = 10. So the length of one side is 10. The length of one side would be the diameter of the circle.
Diameter = 10
The only thing that is left is to find the circumference.
The formulas for circumference are:
C =

d
C = 2

r
So just multiply the diameter by pi (3.14)
10 x 3.14 = 31.4
or 10

(Which would be the answer to your problem)
