Answer:
10x2y3 -4xy2
Step-by-step explanation:
Just take the like terms and separate them-
1) 4x2y3 - (-7x2y3)= 10x2y3
2)2xy2 - 6xy2= -4xy
3)-2y - (-2y)= 0y
Hope this helps :)
I believe it would be B.
Logically, it’s the only one that makes sense,
As 9x10= 90
None of the others have any way to divide or multiply up to the area,
So yes, B.
6.75 is the answer to your question
Answer:
The length of the arc is 1.0467
Step-by-step explanation:
First of all to solve this problem we need to use the circumferenc formula of a circle:
c = circumference
r = radius = 3
π = 3.14
c = 2π * r
we replace with the known values
c = 2 * 3.14 * 3
c = 18.84
The length of the circumference is 18.84
Now we have to divide the 20° by the 360° that a circle has, to know what part of the circle it represents
20° / 360° = 1/18
Now we multiply this fraction by the circumference and obtain the length of the arc
1/18 * 18.84 = 1.0467
The length of the arc is 1.0467
A is 180 degrees, B is 180 degrees, C is definition of complementary angle, D is 180-angle 2, and E is angle 3.
