Y = -2x
because every point of the rhombus vertex will reflect on the opposite vertex.
Bh + hr = 25
you can factor out an h from the left side of your equation:
h(b + r) = 25 ... divide both sides by h
b + r = (25/h) ... subtract r
b = (25/h) - r
₆C₃ is a combination. you can find this setting in the statistics menu of your scientific calculator (i think).
If you don't have a scientific calculator, you can use the following formula:
nCr =
