No. A rectangle MUST have 2 pairs of parallel sides and all equal angles.
A rhombus has 2 pairs or parallel sides with 2 pairs of equal angles.
When you reverse the photo, u can see it goes one by one(86-?-88-89-90)
so it’s 87
Write 2x+3(to the power of 2)+x-4(to the power of 2). Then do the equations and you should get 4x+9+2x+16. Combine like terms and that's your answer. I know it might be weird that it's not like 72 or something, but it's math haha. Your answer should be 6x+25! Make sure you understand this before just writing all of this down. Also, don't be afraid to ask your teacher. They are there to help!
I answered this earlier, 2 + 4 = 6.
