A nonagon has nine sides and a pentagon has five sides. So 4 nonagons and 1 pentagon have 4*9 + 1*5 sides = 41 sides

A heptagon has seven sides and a quadrilateral has four, so 1 heptagon and 3 quadrilaterals have 1*7 + 3*4 = 7 + 12 = 19 sides altogether.

3*12 + 1*7 = 36+7 = 43 sides.

It has 7 sides

A heptagon has seven sides and a pentagon has five. So 2 heptagons and 2 pentagons have 2*7 + 2*5 = 14 + 10 = 24 sides 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

A heptagon has 7 sides and a decagon has 10 sides, so 7+10 = 17 sides

A heptagon has seven sides, and an octagon has eight sides. 4 heptagons and 5 octagons then have (4*7)+(5*8) = 68 sides altogether

3*12 + 1*7 = 36+7 = 43 sides.

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.

A dodecagon has 12 sides, a nonagon has 9, and quadrilateral has 4, and a triangle has 3. So in 1 dodecagon, 2 nonagons, 1 quadrilateral, and 4 triangles there are 1*12 + 2*9 + 1*4 + 4*3 = 12 + 18 + 4 + 12 = 46 sides altogether.
