If x-9 is a factor of x^2-5x-36, what is the other factor? x-4 x+4 x-6 x+6

48 I may be wrong tho

We have the following expression:
 x ^ 2-5x-36
 let's factor the expression:
 (x-9) * (x + 4)
 We check the result multiplying the factorization:
 x ^ 2 + 4x - 9x -36
 x ^ 2 - 5x -36 (OK)
 
 the other factor is:
 X + 4

1. 0.3 •4 is the same as 4 groups of 0.32. 7•0.8 is the same as 7 groups of 0.83. it increases by 0.5 every time, so 0.5x4 it increases by 0.9 every time, so 0.9x5. 0.9•12=10.86. 0.47•5=2.35i can finish the next ones in a separate post
