What are the coordinates of the image of triangle abc after it is translated (x, y ) → (x + 2, y - 4)? ( a0, a1) ( a2, a3) ( a4, a5)

I think you're saying the original triangle has vertices

After the translation the image of the triangle is

if you mean

then it's c. 8, -7/3

but if you mean

then it is

rectangle: 9 1/8 x 4 1/9 = 37 37/72in

parallelogram: b times h= 10.3 x 6.2 = 63.86

trapezoid: a+b/2 times h= 42.5

volume of prism: l times w times h= 36
