Me if your kind(easy)
note: math

A pentagon if it cut by a plane perpendicular to the base, the shape of the cross section is formed a rectangle.

Answer is C. a rectangle.

It depends.

If the prism is "right" with all faces perpendicular to the bases, the cross section will be C. a rectangle.

If one or more faces are not perpendicular to the base, the cross section could be any of the listed choices.

3x + 4y -25 =0 represents the amount of change sianna should recieve

first, you divide the triangle in two, tô form a retangle triangle. after, using pythagoream theorem:

18^2 = 14^2 + (x/2)^2

(x^2/4) + 196 = 324

x^2/4 = 324 - 196

x^2/4 = 128

x^2 = 512

x = √512

x = √2^9

x = 16√2 cm

i hope i you.
