How many sides do 4 dodecagons 4 quadrilaterals and 4 triangles have altogether?
There are 12 sides in a dodecagon, 4 in a quadrilateral, and 3 in a triangle. So in 4 dodecagons, 4 quadrilaterals, and 4 triangles there are 4*12 + 4*4 + 4*3 = 48 + 16 + 12 = 76 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.
How many sides do five pentagons and three quadrilaterals have altogether?
A pentagon has five sides, and a quadrilateral has four sides. So five pentagons and three quadrilaterals have 5*5 + 3*4 sides = 25 + 12 sides = 37 sides.
How many sides do 2 heptagons 3 nonagons and 3 quadrilaterals have altogether?
A heptagon has seven sides, a nonagon has nine, and a quadrilateral has four. So in 2 heptagons, 3 nonagons, and 3 quadrilaterals there are: (2*7)+(3*9)+(3*4) = 14 + 27 + 12 = 53 sides altogether.
