First you calculate the distance between B and D, A and C.
We have the distance between B and D will be: sqrt[(x2-x1)^2+(y2-y1)^2] = 8.5
The distance between A and C will be: 14.14
We have the area of rhombus: 1/2 * 8.5 * 14.14 = 60 square units.

I believe so. one example i can think of is a binomial(idk if it counts as a polynomial tho bc some schools learn different things)such as x+5 multiplied by another binomial such as x+4. (x+5)(x+4) = x^2+9x+20 which is a trinomial.
1. B. 2.C 3.C. these answers are all correct.
