Answer:
Statement 1: A polygon is a square if and only if the polygon has exactly four sides. FALSE
Statement 2: A polygon has exactly five sides if and only if the polygon is a pentagon. TRUE
Statement 3: A polygon has exactly four sides if and only if the polygon is a rectangle. FALSE
Step-by-step explanation:
In order to prove if a biconditional statement is true if both the conditionals are true, otherwise is false.
In this case you have to use geometry shapes definitions to determine if the conditionals are true or false.
The statement 1 is false because by definition a polygon is a square if the polygon has four sides of the same size forming rect angles. A polygon with four sides is not necessary a square.
The statement 2 is true because by definition a pentagon is a polygon with five sides .
The statement 3 is false because there are differents polygons with four sides (quadrilaterals). For example a square, rhombus. Not all the quatrilaterals are rectangles.
Answer:
neither of the endpoints.
Step-by-step explanation:
Given the solution
2 < x < 24
Indicates that the solutions to the original inequality are between 2 and 24 but not including 2 and 24
If the solution had been
2 ≤ x ≤ 24
Then both 2 and 24 would be included in the solution
Answer:
The volume is 75.4 ft.
Step-by-step explanation:
C=2piR. C=2(3.14)(8.2). C=6.28(8.2). C= 51.496. But we have to round to the nearest hundredth which is the second place to the right of a decimal. So now C=51.50 (since 49+1=50) :) hope this helps
