Answer:
4
Step-by-step explanation:
If two chords intersect externally, then the product of the length of the chord and the length of the part outside the circle is a constant.
Thus from the figure,
we can deduce that:
8×3=6×x
collecting the like terms together we get:
24=6x
x=4
Answer:
x = 3
Step-by-step explanation:
The smaller triangle and larger one are similar, so corresponding sides are proportional.
8/4 = (8 +(x -1))/5
10 = x +7 . . . . . . . . . multiply by 5 and simplify
3 = x . . . . . . . . . subtract 7

<em>Alternate solution</em>
The short segments are also proportional:
(x -1)/(5 -4) = 8/4
x -1 = 2 . . . . simplify
x = 3 . . . . . . add 1
Answer:
Vertex: (13/6,-133/12)
Axis of symmetry: x=13/6
y-intercept: y=3
Step-by-step explanation:
23/5, 5/2, 31/9, and 19/7
All you have to do is multiply the whole number by the denominator and add the numerator. For example:
5 3/6 5*6 is 30 +6 is 36
therefore the improper fraction is 36/6
Answer:
P = 20 cm
Step-by-step explanation:
the perimeter (P) is the sum of the 4 sides (s) of the square
the sides of a square are congruent , then
P = 4s = 4 × 5 = 20 cm
