Let us consider the number of edges = x
we know that a triangle will have 3 edges and a square will have 4 edges. Using this details we can form an equation.
3x + 4x = 8484
7x = 8484
x = 8484/7
= 1212
Then
Number of square tiles = 1212/4
= 303
So there are 303 square tiles in the box. I hope the procedure is clear enough for your understanding. You can always use this method for solving similar problems.

Answer:
x+6y=9 - > y= (-1/6)x+(3/2)
x - 6y=-9 - > y= (1/6)x+(3/2)
-9x - 6y = -9 - > y = (-3/2)x +(3/2)
3x - y = - 6 - > y= 3x + 6
-63x - y = - 6 - > y = - 63x + 6
3x + y = 6 - > y = -3x +6
Step-by-step explanation:
The standard form of the equation of a line is: y=ax+b
You seperate y from x and the constant value(the number) and then devide tge equation with the coefficient of y. Obviously it mustnt be division by zero.

10/12 = (3x+2)/(5x-0.4)
10(5x-0.4) = 12(3x+2)
50x - 4 = 36x + 24
50x - 36x = 24 + 4
14x = 28
x = 28/14
x = 2
QS = 3x + 2 = 3*2 + 2 = 6 + 2 = 8
SR = 5x - 0.4 = 5*2 - 0.4 = 10 - 0.4 = 9.6
Answer is QS=8, SR=9.6

Answer:
17.32 meters
Step-by-step explanation:
We realize the cable is the hypotenuse and then that height would be the new side, the measurement would not change once hypotenuse is found.
60 deg is the lower angle as it meets the ground base.
Sin (60) = 0.8660254038 x 20 = 17.32m
0.86 reduction = a
We use Sin (60) = a a x 20 to find the pole as above.
We use Tan (60) x base to find 20m to check hypotenuse if base was given = length of floor x tan(60) etc.
