The answer is 10 you see 6 people are in both of the classes so you have to subtract 6 from the 12 and 16 12+16-6=22
32-22=10
<u>Given</u>:
The given circle with center at C. The lines AB and AD are tangents to the circle C.
The length of AB is (3x + 10)
The length of AD is (7x - 6)
We need to determine the value of x.
<u>Value of x:</u>
Since, we know the property of tangent that, "if two tangents from the same exterior point are tangent to a circle, then they are congruent".
We shall determine the value of x using the above property.
Thus, we have;
AB = AD
Substituting the values, we get;
![3x+10=7x-6](https://tex.z-dn.net/?f=3x%2B10%3D7x-6)
Subtracting both sides of the equation by 7x, we get;
![-4x+10=-6](https://tex.z-dn.net/?f=-4x%2B10%3D-6)
Subtracting both sides of the equation by 10, we get;
![-4x=-16](https://tex.z-dn.net/?f=-4x%3D-16)
Dividing both sides of the equation by -4, we get;
![x=4](https://tex.z-dn.net/?f=x%3D4)
Thus, the value of x is 4.
Answer:
x²-10x=area
Step-by-step explanation:
Area= length×width
Length: x
Width: x-10
Area= x(x-10)= x²-10x
