Answer:
27 I think just divide 81 by 3
F(2) is same thing as saying x =2
So just plug in 2 for x and solve for x
3*(2)^3 - 12*(2)^2 =
3*8 - 12*4 =
24-48 =
-24

3/16? Please make this more clear
3/16 = 0.1875
Answer:
256 cm^2
Step-by-step explanation:
The area of the rectangle is the product of its length and width.
A = (16 cm)(10 cm) = 160 cm^2
The area of each triangle is half the product of its base and height.
A = (1/2)(16 cm)(6 cm) = 48 cm^2
__
Then the area of the rectangle and 2 triangles is ...
160 cm^2 + 2(48 cm^2) = 256 cm^2
The area of the composite figure is 256 cm^2.
Lets say that you had a triangle that had an area of 64, each side being 4 (4X4X4=64) then you cut each side in half 2X2X2 the percentage decrease would be 87%
