The equation factors as
.. (x +3)(x +4) = 0
By the zero-product rule, the roots are
.. x1 = -4
.. x2 = -3
Tiled floor with 225 square tiles means the area of the square room is 225.
Formula needed: A = (side)^2 or in short
A = s^2.
We need to find s.
225 = r^2
sqrt{225} = sqrt{r^2}
15 = r
There are 15 tiles are along an edge of the room.
Answer:
D is the polynomial. A is a binomial with only 2 terms, as is B and C. D is a trinomial with three terms, and is considered a polynomial.
