9 is a parallelogram because parallelograms have parallel sides. and for 10 set 7x+3=3x+35 because its a rectangle and the side lengths are equal. solve to get
4x=32
x=8
x=x, so plug in 8for x for bc=2x+5
16+5=21
then plug in x to both equations just in case (ab and dc)
i got 59 and 59)
so 59 and 21 are the side lengths, so now use that calculator for the Pythagorean theorem.62.63 about.cuz its a right triangle.
The answer to the equation is approximately 536.91
17/36 hope that helps if u get it wrong I am sry bc I am not good at math but hope that helps
