Any fraction that can be simplified to 1/4 would work. I don't have a model to shade, but I can give you some examples. 2/8, 3/12, 4/16, 5/20... I hope this helps!
You are basically just adding, so combine like terms.
3x^2 + 5x^2 = 8x^2
6x - 2x = 4x
4 - 8 = -4
So the answer is D.
Hello!
P = 2,1cm + 2,1cm + 1cm + 3,3cm + 1cm => P = 4,2cm + 1cm + 3,3cm + 1cm => P = 5,2cm + 3,3cm + 1cm => P = 8,5cm + 1cm => P = 9,5cm
Answer: D. 9,5cm
Good luck! :)
x=8.9 because when you square it and divide you get 39.6.. rounded to 40.
