Each decagon has 10 sides, each nonagon has 9 sides and each pentagon has 5 sides. 4 decagons make 40 sides, 2 nonagons make 18 sides and 2 pentagons make 10 sides. When you add them all up together, you get 68 sides in total.

How many sides do 3 hexagons and 3 nonagons have altogether?
A hexagon has six sides, and a nonagon has nine. Three hexagons and three nonagons then have (3 x 6) + (3 x 9) = 18 + 27 = 45 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 4 decagons 5 heptagons 5 nonagons and 1 octagon have altogether?
A decagon has 10 sides, a heptagon has 7, a nonagon has 9, and an octagon has 8. So 4 decagons, 5 heptagons, 5 nonagons, and 1 octagon have 4*10 + 5*7 + 5*9 = 1*8 sides = 40 + 35 + 45 + 8 = 128 sides
How many sides do 2 decagons 1 hexagon 4 nonagons and 2 triangles have altogether?
A decagon has ten sides, a hexagon has 6, a nonagon has nine, and a triangle has three. So 2 decagons, 1 hexagon, 4 nonagons, and 2 triangles have 2*10 + 1*6 + 4*9 + 2*3 = 20 + 6 + 36 + 6 = 68 sides altogether.
How many sides do 5 decagons and 4 triangles have altogether?
A decagon has ten sides and a triangle has three, so 5 decagons and 4 triangles have (5*10)+(4*3) = 62 sides altogether.
How many sides do 5 decagons and 3 pentagons have altogether?
A pentagon has five sides, and a decagon has ten sides. So 3 pentagons and 5 decagons have (35)+(510) = 65 sides altogether
How many sides do 3 hexagons and 3 nonagons have altogether?
A hexagon has six sides, and a nonagon has nine. Three hexagons and three nonagons then have (3 x 6) + (3 x 9) = 18 + 27 = 45 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 nonagons and 2 decagons have in all?
38 sides
How many sides do 4 decagons 5 heptagons 5 nonagons and 1 octagon have altogether?
A decagon has 10 sides, a heptagon has 7, a nonagon has 9, and an octagon has 8. So 4 decagons, 5 heptagons, 5 nonagons, and 1 octagon have 4*10 + 5*7 + 5*9 = 1*8 sides = 40 + 35 + 45 + 8 = 128 sides
How many sides do 4 dodecagons 3 pentagons and 2 decagons have in all?
There are 12 sides in a dodecagon, 5 in a pentagon, and 10 in a decagon. So in 4 dodecagons, 3 pentagons, and 2 decagons there are 4*12 + 3*5 + 2*10 = 48 + 15 + 20 = 83 sides altogether.
How many sides do 2 pentagons 3 nonagons and 2 hexagons have in all?
They have 49 sides.
How many sides do 1 heptagon and 2 nonagons have altogether?
A heptagon has seven sides and a nonagon has nine, so in 1 heptagon and 2 nonagons there are 7+(2*9) = 25 sides altogether.
How many sides do 4 decagons 1 hexagon 3 nonagons and 2 quadrilaterals have altogether?
1*6 + 2*4 + 4*10 + 3*9 = 6 + 8 + 40 + 27 = 81
How many sides do 2 decagons 1 hexagon 4 nonagons and 2 triangles have altogether?
A decagon has ten sides, a hexagon has 6, a nonagon has nine, and a triangle has three. So 2 decagons, 1 hexagon, 4 nonagons, and 2 triangles have 2*10 + 1*6 + 4*9 + 2*3 = 20 + 6 + 36 + 6 = 68 sides altogether.
How many sides do 5 decagons and 4 triangles have altogether?
A decagon has ten sides and a triangle has three, so 5 decagons and 4 triangles have (5*10)+(4*3) = 62 sides altogether.
How many sides do 3 decagons and 5 triangles have altogether?
There are ten sides in a decagon and three sides in a triangle. So in 3 decagons and 5 triangles there are 3*10 + 5*3 = 30 + 15 = 45 sides altogether.
