Answer:
F.] - 5x - 2
Step-by-step explanation:
( 12 - 4 + 20x )
First simply every possible term in the bracket.
= ( 8 + 20x )
Now open the brackets and multiply with the other two terms.
= - 
- 
= - 2 - 5x
Answer:
Step-by-step explanation:
If you're supposed to find the measure of the arc:
The minor arc CD has the same measure as the central angle it subtends. In this case, arc CD has measure 50º. In radians, that's
50º * (π/180 rad/º) = 5π/18 rad
If you instead meant to ask about finding the length of the arc CD, recall that arc lengths and their subtended central angles occur in a fixed ratio equal to the ratio of the circle's total circumference to 2π rad. In other words, if <em>L</em> is the length of the minor arc CD, then
<em>L</em> /(5π/18 rad) = 2π (7 cm) / (2π rad)
==> <em>L</em> = 35π/18 cm
(Notice that arc measure is given radians, while arc length is given in cm, which is why I offer two different answers here.)
Answer:
Negative
Step-by-step explanation:
When you multiply a negative number by a positive number then the product is always negative.
