The real answer is 72 .
First, find the number of sides for each group of shapes.
5 pentagons: 5 × 5 = 25
3 hexagons: 3 × 6 = 18
2 decagons: 2 × 10 = 20
1 nonagon: 1 × 9 = 9
Now add to find the total number of sides:
25 + 18 + 20 + 9 = 72

∙ 7y agoA decagon has ten sides, and a hexagon has six. So in 5 decagons and 3 hexagons there are 5*10 + 3*6 = 50 + 18 = 68 sides altogether.

How many sides do 4 decagons and 5 hexagons have altogether?
A decagon has 10 sides, and a hexagon has 6. So in 4 decagons and 5 hexagons there are (4*10)+(5*6) = 70 sides
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 octagons have altogether?
A decagon has ten sides and an octagon has eight, so in 3 decagons and 5 octagons there are (3*10)+(5*8) = 30 + 40 = 70 sides altogether.
How many sides do 4 decagons and 1 quadrilateral have altogether?
4 decagons = 4*10 = 40 sides 1 quadrilateral = 4 sides Total 40+4 = 44 sides.
How many sides do 5 decagons and 5 heptagons have altogether?
A decagon has 10 sides and a heptagon has 7. So five decagons and five heptagons have 5*10 + 5*7 = 50 + 35 = 85 sides.
How many sides do 4 decagons and 5 hexagons have altogether?
A decagon has 10 sides, and a hexagon has 6. So in 4 decagons and 5 hexagons there are (4*10)+(5*6) = 70 sides
How many sides does 5 hexagons 3 octagon and 2 decagons have in all?
There are 74 sides in all.
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 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.
How many sides do 3 decagons and 5 octagons have altogether?
A decagon has ten sides and an octagon has eight, so in 3 decagons and 5 octagons there are (3*10)+(5*8) = 30 + 40 = 70 sides altogether.
How many sides do 4 decagons and 1 quadrilateral have altogether?
4 decagons = 4*10 = 40 sides 1 quadrilateral = 4 sides Total 40+4 = 44 sides.
How many sides do 3 hexagons and 3 octagons have altogether?
A hexagon has six sides, and an octagon has eight. 3 hexagons and 3 octagons have 3*6 + 3*8 sides = 18 + 24 sides = 42 sides altogether.
How many side does 3 hexagons have altogether?
3*6 = 18 sides
How many sides do 5 decagons and 5 heptagons have altogether?
A decagon has 10 sides and a heptagon has 7. So five decagons and five heptagons have 5*10 + 5*7 = 50 + 35 = 85 sides.
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 5 decagons and 5 octagons have altogether?
A decagon has 10 sides and an octagon has 8. 5*8 + 5*10 = 90 sides
