By the Intersecting Secants Theorem we have
2x(2x+7)=x(x+23)
4x^2+14x=x^2+23x
3x^2=9x
3x=9
x=3
Since DY is length 2x,
the length of DY is 6.
Answer:
c=9
Step-by-step explanation:
71.25km
All you have to do is multiply 12.5x5.7=71.25
Answer:
10 ways
Step-by-step explanation:
Here, we want to calculate the number of ways in which the selection can be made
We have this as follows;
Since we have style starting line up already, it means a choice of 5 has been made from the 13 already. What is left is to make a selection of 3 from 5
To do this, we simply apply the combination formula
that would be;
5 C 3 = 10 ways
