(8c-5) (6c+4)
Put 8 into 6 and 4
48c^2+24
Put -5 into 6 and 4
-30c-20
Put those together
48c^2+24=-30c-20
Simplify
48c^2+24=-30c-20
-24. -24
48c^2=-30c-44
+30c. +30c
78c^3=-44
———- ——
-44. -44
C= 26
Never, just by the definition of scalene triangle and regular polygon. A scalene triangle has three different angles, and a regular polygon is a polygon who's angles are all congruent. Therefore, a scalene triangle is never a regular polygon.
Answer:
The second table shows the proportional relationship
Step-by-step explanation:
As we can see in the table that the first row has the multiples of 5. Th second row shows the multiplier. Which means that if we multiply 5 to the second row, we will get its answer in the firs row such as:
5 10 15 20 25
1 x 5 2 x 5 3 x 5 4 x 5 5 x 5
The point

lies on the unit circle.
The reference angle for 245° is 65°.
Since 245° lies in the third quadrant,
cosine is negative and sine is negative
Therefore 245° intersect the unit circle at

In terms of x and y, 245° intersects the unit circle at
