Answer:
B
Step-by-step explanation:
As we know when factoring in complete from when it is given to us like this we erase one of the double terms, in this case is x+9 so after erased, it is
5x-7(x+9)
which basically is (5x-7)(x+9)
So that is the answer, thank you .
(x=9)x (5x-7)
Step-by-step explanation: Given the expression sin(11pi/2 +x) =-1/2. Take the arcsin of both sides. sin⁻¹[sin(11pi/2 +x)]
