I'd use synthetic div. here, with 2 as my divisor:
________________
2 / 1 -11 18
2 -18
----------------------------
1 -9 0
Note that the coefficients of the missing factor are given here and are 1 and -9. Thus, (x-9) is the missing factor.
15+70+45=130 :)) that’s how u calculate the perimeter just add them all together.
The answer is 148.8
120 · 24 = 120 · 0.24 = 28.8
120 = 28.8 = 148.8
