I'm having trouble with the formula for triangular prisms which is what we are learning in class this week.

Solve this system of equations. 12x − 18y = 27 4x − 6y = 10

Rhombus adef is inscribed into a triangle abc so that they share angle a and the vertex e lies on the side bc . what is the length of the side of the rhombus if ab=c, and ac=b.

Which equation is y = -6x2 + 3x + 2 rewritten in vertex form?
