The answer is -32. This is because when you multiply to negatives it becomes a positive. So its 8*-4 making the answer be -32.
3 × 
expressing as a whole number, using the digits available, we obtain
3
Now consider the position of the decimal point in the original 0.003
To get it back to where it should be we require to move the decimal point 3 places to the left , denoted by a negative exponent
0.003 = 3 × 
You would have to first times .03 times 10 then take that times 30,000 which should equal 900
Ok, 6×25=150, since there are 6 sides, the answer is 150cm.
The answer is 12 including both sides and angles.
When you cut a square piece of paper from one point to the opposite point it should make two triangles.
Thus each triangle has 3 sides and 3 angles so two triangles has 6 angles and 6 sides
So 12, sides and angles added together.
