Given: wxyz is a parallelogram
Zx=wy
prove: wxyz is a rectangle

i think it might be a but you might want a second opinion

it would open into a square depending on the type of envelope i’m not sure about the second part

step-by-step explanation:

well if you round, things become much more simple. round 5.95 to 6, 4.25 to 4, and 1.05 to 1. now, add 6+4+1 and that would equal 11. so the items together would equal to about $11.
