-6r(4r - 5) - 2(r - 2)
(-6r).4r - 5.(-6r) - 2.r - 2.(-2)
-24r² + 30r - 2r + 4
-24r² + 28r + 4
Answer:
Step-by-step explanation:
Area for triangle A is 12 Triangle B is 12 triangle C is 12
The area is related to the base and it's corresponding height because they all equal each other. The triangle has added on parts and it shows they are all equal but are in a different direction.
The area of the shaded triangle is 18 because the base is 6 and the height is 6.
A, B, E

Take a look at the attachment below. It may help!
With this sector we can create a proportion to find the area watered by the sprinkler. 85 degrees over a total 360 degrees would be simplified to the following -
17 / 72 = ( About ) 4.235
Thus, we can calculate the area of the circle with a range of 5 meters radius, and divide by about 4.235 to receive the area watered by the sprinkler, or the area of the sector -

22 + 42/22 = 23.9090909091
So, I think the answer might be 23
