Answer:

x = 7

Step-by-step explanation:

The product of secant lengths to the two intersection points is the same for both secants.

(AD)(AE) = (AB)(AC)

8(8+10) = (x-1)(x-1 +x+11)

144 = 2x^2 +8x -10

x^2 +4x -77 = 0

(x +11)(x -7) = 0

Solutions to this quadratic are x = -11, x = 7. (These values make the factors zero.) Only the positive solution is useful here

x = 7

At the car show Inez saw a truck wheel shaped like a circle with a radius of 3 ft. She wants to know the area of the truck wheel

Nadusha1986 [10]

Answer:

$28.27ft^2$

Step-by-step explanation:

To solve this problem, we can use the area of a circle formula:

$A=\pi r^2$

<em>r = radius</em>

Lets plug the values into the equation:

$A=\pi (3^2)$ Calculate $3^2$

$A=\pi (9)$ Multiply $\pi$ and 9 together

$A=28.27$

The area of the truck wheel is $28.27ft^2$
