How many sides do 3 dodecagons and 2 quadrilaterals have altogether?
A dodecagon has 12 sides, and a quadrilateral has 4 sides, so 3 dodecagons and 2 quadrilaterals have 3*12 + 2*4 = 36 + 8 = 44 sides altogether.
How many sides do 4 decagons 5 dodecagons and 3 pentagons have altogether?
A decagon has 10 sides, a dodecagon 12, and a pentagon 5. So 4 decagons, 5 dodecagons, and 3 pentagons have 4*10 + 5*12 + 3*5 sides = 40 + 60 + 15 = 115 sides altogether.

How many sides do 2 quadrilaterals and 3 pentagons have altogether?
A quadrilateral has four sides and a pentagon has five. So 2 quadrilaterals and 3 pentagons have 2x4 +3x5 sides = 8 + 15 = 23 sides altogether.
Is a trapezoid a triangle?
