Consider the circle where QR = 7 units and UT= 4 units. What is the value of X, if x represents the length of segment ST? A. 15
julia-pushkina [17]

Option C:

x = 6  units

Solution:

QR = 7 units, RS = 5 units, UT = 4 units and ST = x

<em>If two secants intersect outside a circle, the product of the secant segment and its external segment s equal to the product of the other secant segment and its external segment.</em>

⇒ SR × SQ =  ST × SU

⇒ 5 × (5 + 7) =  x × (x + 4)

⇒ 5 × 12 =  x² + 4x

⇒ 60 =  x² + 4x

Subtract 60 from both sides.

⇒ 0 = x² + 4x - 60

Switch the sides.

⇒ x² + 4x - 60 = 0

Factor this expression, we get

(x - 6)(x + 10) = 0

x - 6 = 0, x + 10 = 0

x = 6, x = -10

Length cannot be in negative measures.

x = 6 units

Option C is the correct answer.

               t = 30a  +  150 . 

' t ' is the total cost of treatment. 
' a ' is the number of appointments. 
The $150 is paid only once. 

I hope Pedro gets better fast.  Poor little guy.
______________________________________

Oh, I see.
Now you're saying that she pays the $150 at every appointment.

So the equation is actually
