I don't know where to find those number on my keyboard so I will subsitute
€=x£=y¥=zso
1x=0.89y
and 1y=48z
first find conversion factor from z to x
1x=0.89y
y=48z
subsitute 48z for y in first equation
x=0.89(48z)
x=42.72z
divide both sides by 42.72
x/42.72=z
256z is wanted so
multiply both sides by 256
x/1 times 256/42.72=256z
5.99251x=256z
there are aprox 5.99x in 256z or about 6

Answer:
11. x = -3+√37 ≈ 3.08276
12. x = 11.2
13. x = -6 +6√5 ≈ 7.41641
Step-by-step explanation:
In each case, the relation of interest is ...
(distance to circle near) × (distance to circle far) = (distance to circle near) × (distance to circle far)
When there is only one point of intersection of the secant with the circle—because it is a tangent—then the product is the square of the length of the tangent.
11. 2(2+12) = x(x +6)
x² +6x -28 = 0
(x +3)² -37 = 0
x = -3+√37 ≈ 3.08276
12. 5(5+x) = 9(9)
5x +25 = 81
x = 56/5 = 11.2
13. x(x +12) = 12(12)
x² +12x -144 = 0
(x +6)² -180 = 0
x = -6 +√180 ≈ 7.41641

<em>Comment on this secant rule</em>
This rule turns out to apply whether the point of intersection of the secant lines is outside the circle (as in these problems) or inside the circle (as in problem 9). The product of the two distances from the point of intersection to the circle is a constant for a given pair of intersecting secants/chords.
