Sides given by
Opposite sides must be equal
Let's check once

Find sides now
- 10in
- 2+2=4in
- 2+5=7in
- 2(2)+3=4+3=7in
One pair of opposite sides are equal but others not .
Answer:
(−∞,−82)
Step-by-step explanation:
Eighty-two less than r, r−82 is less than <−164.
Now we can solve the inequality by adding 82 to each side.
r−82r−82+82r<−164<−164+82<−82
In interval notation, we write this as (−∞,−82).

When a polygon is regular, that means that all of its sides are the same length and all of its angles are the same. A heptagon has seven sides and you know that all of them measure 3 inches. You can find the perimeter by adding all of the side measures together, so 3 + 3 + 3 + 3 + 3 + 3 + 3, or 3 x 7. So, the perimeter of the heptagon is 21 inches.
