How many sides do 4 decagons 4 heptagons and 3 octagons have altogether?

A decagon has ten sides, a heptagon seven, and an octagon eight. So in 4 decagons, 4 heptagons, and 3 octagons there are 4*10 + 4*7 + 3*8 = 40 + 28 + 24 = 92 sides altogether.

Can a semi-regular tessellation be made from octagons and rhombi?

Strictly speaking, no, because a semi-regular tessellation must be based on regular polygons and rhombi are not regular polygons. However, octagons and rhombi can be used to make a non-regular tessellation.

What are some examples of polygons?

How many sides do 5 heptagons 2 hexagons 4 nonagons and 3 octagons have altogether?

A heptagon has seven sides, a hexagon six, a nonagon nine, and an octagon eight. So in 5 heptagons, 2 hexagons, 4 nonagons, and 3 octagons there are (5*7)+(2*6)+(4*9)+(3*8) = 35 + 12 + 36 + 24 = 107 sides altogether.
