If a polygon is a rectangle, then it is a square. If a polygon is a square, then it is a rectangle. If a polygon is not a rectangle, then it is not a square.
Answer:
Option D
Step-by-step explanation:
we have
-----> equation A
-----> equation B
Solve the system by elimination
Multiply both sides equation A by -1
-----> equation C
Adds equation C and equation B
<em>Find the value of x</em>
substitute the value of y in either equation
The solution is the point (-1,2)
In this problem Option A,B and C are correct
The option D not result in a system with a pair of opposite terms
because
Multiply both sides of equation B by -3
-----> equation C
Multiply both sides of equation A by 5
----> equation D
so
equation C and equation D not have a pair of opposite terms
Answer: Length = 12cm , width = 21cm
Step-by-step explanation:
Let the length be x , then the width is x + 9, That is
Length = x
Width = x + 9
The formula for calculating the perimeter of a rectangle is given by:
Perimeter = 2 ( Length + Width )
substituting the values , we have :
66 = 2 ( x + x + 9 )
66 = 2 ( 2x + 9 )
divide through by 2
66/2 = 2x + 9
33 = 2x + 9
subtract 9 from both sides
33 - 9 = 2x
24 = 2x
divide through by 2
therefore :
x = 12
This means that
Length = 12cm
Width = 12 + 9 = 21 cm
