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.
30 minutes. the easiest way is to use the opposite of the fraction. divide 25 / 5= 5. now multiply by 6. 5*6= 30.
Answer: It’s 5 if it’s the two legs
Step-by-step explanation:
Use the Pythagorean Theorem
You need to state which one is the height.
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
<span>t = 180a</span>
