A parallelogram is a shape with two sets of parallel lines and that shape has two sets of parallel lines so it’s a parallelogram and all quadrilateral shapes are parallelogram but not all parallelograms are quadrilaterals..
I hope this help hun


You have to first substitute every variable into its spot in the equation.

Then solve.
4X,X^2,_
Common difference=12
second term - first term=12
X^2-4x=12
subtract 12 from both sides
X^2-4X-12=12-12
X^2-4X-12=0
now its a quadratic equation, so use either factor method or quadratic formula,
X^2-6X-2X-12=0
take common
x(X-6)-2(x-6)=0
x-2)(x-6)=0
so x is either 2 or 6
now use them to find the third term
X=0 and y=0, set them equal to each other
