B because first you do the two triangles which =3 then you get the area for the square in the middle which is 15 then you add them up to get 18
Answer:
a. yes
b. no
c. yes
d. yes
Step-by-step explanation:
For a, 27 + 38 can be broken apart. 27 is broken up by adding smaller numbers (20 + 7 = 27) and the same is done with 38 (30 + 8 = 38), so A and C shows a way to add 27 and 38. In C, the numbers are just put into a different order. B is not a way to add 27 and 38, because the sum is different.
27 + 38 = 65, however 20 + 70 + 38 = 128. The addition problem for D is a way to solve for 27 + 38, because it is broken up differently than A and C. They instead added the 20 and 30 together first, then split up 15 (from 8+7) into 10 and 5. So D is a way to solve, because it gets the same answer as 27 and 38 :D

Answer:
The correct option is 1. The circumference of circle is 12π units.
Step-by-step explanation:
From the given figure it is clear that the radius of the circle is6 units.
The circumference of a circle is
Where, r is the radius of the circle.
The circumference of the circle is
The circumference of circle is 12π units.
Therefore option 1 is correct.
Answer:
-1.5
Step-by-step explanation:
- 2 (y-2) = 4y + 8 - 2 (-4y - 3)
- 2y-4=4y+8+8y+6
- 2y-4=12y+14
- -4-14=14y-2y
- -18=12y
- y=-18/12
- y=-1.5
