A triangle abc with vertices a (6,8) b(6,12) and c(10,12) is rotated 180 degrees. what are the coordinates of B

1 answer:

4 0

The rule for a rotation by <span>180
</span>(x,y)→(−x,−y)
so B<span>(6,12) will be B'(-6, -12)

answer

</span>B'(-6, -12)

Anyone know how to do area or volume? Any help will do! thanks

exis [7]

Answer:

Volume: x(x+6)(x+2) Area: $x^{2}$ + 8x +12

Step-by-step explanation:

Volume Explanation:

To find the volume of a 3d figure, we must multiply the length, width, and the height. Therefore we multiply (x)(x+6)(x+2)= $x^{3}$ + 8 $x^{2}$ + 12x. Simplify this equation and we will get x(x+6)(x+2) for the formula to find the volume of the 3D figure.

Area:

To find the area of a 2D figure, we must multiply length x height. Therefore, we multiply the equations (x+6)(x+2)= $x^{2} + 2x + 6x +12$ to get a final answer of $x^{2} +8x +12$ . This will be the formula when you find the area of the 2D figure in question.
