(12-3)/(3-6)=9/(-3)=-3
answer D
Option A:
x = 3
Solution:
Special segments in a circle:
<em>If two secant segments are drawn to a circle from a exterior point, then the product of the measures of one secant segment and its external secant segment is equal to the product of the measures of the other secant segment and its external secant segment.</em>
⇒ 9 × 4 = x × 12
⇒ 36 = 12x
Divide by 12 on both sides, we get
⇒ 3 = x
Switch the sides of the equation.
⇒ x = 3
The value of x is 3.
Hence option A is the correct answer.
Answer:
y = √ x + 4
The domain of a function is the value in which you put in the function will make it undefined.
To find the domain equate the function to zero
That's
√x + 4 = 0
square both sides
x + 4 = 0
x = - 4
The domain of the function is x E R except - 4
Hope this helps
Answer:
i think 9 but 6 could also be right
Step-by-step explanation:
18-12=6------18-3=15-------15-3=12-----------12-3=9
