Factor completely. x^2−5x−36 enter your answer in the box.

We can factor this using the AC method.

We can split the middle term using the factors 4 and -9

x^2 + 4x - 9x - 36

Factor by grouping.

x(x + 4) - 9(x + 4)

  21.3

step-by-step explanation:

multiplying the given equation by c/sin(25°), we get

  c = 9/sin(25°) ≈ 21.2958 ≈ 21.3

we assume "c" is the length of ab, the side opposite angle c in triangle abc.

part d
