Will give brainliest to whoever answers !

what is the shape of the cross section of the figure that is perpendicular to the rectangle base and passes through the top vertex of the figure?

a.) a parallelogram that is not a rectangle

b.) a rectangle

c.) a triangle that must have the same dimensions as one of the faces

d.) a triangle that does not have the same dimensions as one of the faces

step-by-step explanation:

what are the things "represented below"?

step-by-step explanation:

nobody can if you dont give the choices

c.

step-by-step explanation:

she should of added 9^2 and 12^2. that is because it is a^2+b^2=c^2. c^2 is the hypotenuse and should always be bigger than the other two numbers. which is why she should of added 9 squared and 12 squared together instead of 15 squared.

my guess would be b and d, but i didn’t actually get out the pen and paper. lol
