Answer:x/5 + 2b/5
Step-by-step explanation:
9a-2b=c+4a solve for a
9a-2b=c+4a
add -4a to both sides
9a-4a-2b=x+4a-4a
5a-2b=x
add 2b to both sides
5a-2b+2b=x+2b
5a= x+2b
divide by 5
5a/5 = x/5 +2b/5
a= x/5 + 2b/5
Answer:
The only correct option is:
Option B. The perpendicular bisectors for each side are the only lines of reflection.
Step-by-step explanation:
A regular polygon has an odd number of sides. Which statement is true about the lines of reflection for the polygon that will map the shape onto itself?
A.
Lines that connect pairs of opposite vertices are lines of reflection.
B.
The perpendicular bisectors for each side are the only lines of reflection.
C.
The lines of reflection are parallel to the sides of the polygon.
D.
There are no lines of reflection.
The only correct option is:
Option B. The perpendicular bisectors for each side are the only lines of reflection.
Answer:
C
Step-by-step explanation:
Using sum/difference to product identity
• sin x - sin y = 2 cos(
) sin (
)
with x = 4Θ and y = 2Θ
Then
sin(4Θ) - sin(2Θ)
= 2 cos(
) sin(
)
= 2cos(3Θ)sinΘ → C
90 is the outlier
for future reference, outliers are numbers much larger or much smaller than the other numbers in a set
for example
2,3,4,21,6
or 90,87,94,12,99
Equation: C=dπ
C=6·3.14
C=18.84
