what is k?
Answer:
x = 5
Step-by-step explanation:
7x is a secant- secant angle and has measure equal to half the difference of the intercepted arcs, that is
7x = 0.5(22x + 10 - 50)
7x = 0.5(22x - 40) ← distribute
7x = 11x - 20 ( subtract 11x from both sides )
- 4x = - 20 ( divide both sides by - 4 )
x = 5
Answer:
B
Step-by-step explanation:
Firstly the unfilled circle means that it is not equal to
If you read the scale the unfilled circle is at -1 and the arrow is pointing left.
This means that x is smaller than -1 or -1 is greater than x read in the form x<-1
The filled circle means x can be equal to, in this case, 4. The arrow is pointing right so x is greater or equal to 4
x≥4
Therefore the answer is b
Hope this helps
Answer:
x³+3x²+4x+12
Step-by-step explanation:
you are going to write both equations and distribute. if there are like terms, combine them and then put it order.
(x + 3) × (x² + 4)
x³ + 4x + 3x² + 12
when putting in order, you want the highest power to the left and then the lowest power to the right.
so
x³+3x²+4x+12
The answer is going to be x=22
