If a cube is divided into two equal parts by a plane parallel to a face of the cube, which of the following best describes the cross-section of the cube?
a rex]ctangle
b triangle
c square
d scalene triangle

C:  square

Step-by-step explanation:

Look at a die and imagine that you're cutting it in half parallel to any one side.  What figure would you see in the plane you just cut?

It'd be a square.  Option C.

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3

i hope this !

1/4 because there is 4 grades.
