Given: Alana claims that not all 4-sided polygons with 2 pairs of equal sides are parallelograms
To check: whether she is correct or not.
Solution:
Any two-dimensional figure formed using straight lines is known as a polygon. Triangles, quadrilaterals are examples of polygons.
A parallelogram is a quadrilateral in which opposite sides are parallel.
Kite is a polygon made up of four sides with two pairs of equal sides that are adjacent to each other but it is not a parallelogram as its opposite sides are not parallel.
Add the five to each side. then square it to get rid of the square root 2x+13=(5+x)^2 2x+13=x^2+10x+25 2x=x^2+10x+12 x^2+8x+12=0 (x+6)(x+2) x+6=0 x+2=0 answers are -2 and -6, however, when pluging -6 in it doesnt work, so it is only -2.
