Give 3 example of cause and effect
Here is one way. Start with: 4n - 7 = 5 - 2n add 2n to both sides to give: 6n - 7 = 5 add 7 to both sides to give: 6n = 12 divide both sides by 6 to give: n = 2
Adding the lengths of the straight sides of any polygon will give its perimeter. In the case of regular polygons it will be the length of the side multiplied by the number of sides. But in the case of a non-regular polygon all the individual sides' lengths will be added to give you the perimeter.
No. Adding the sides will give you the perimeter. Volume = Length x Width x Height
Yes. This is because: Since the opposite sides are congruent, that would mean 2 sides are congruent with the others and 2 more sides are also. This takes up all four sides, which makes all of the sides congruent in the square. If you still do not get it, follow up on Mathisfun.com and it will give you explanations on why. -Savanna :D
