<span>75.4615 is the answer I got. hope this helped let me know if the answer is correct </span>
I’m not sure if the 15 is the question number but if it is the answer is 32. use PEMDAS
Answer:
1st box: Asso. prop= m+(4+x)
2nd box: Comm. Prop= m+4=4+m
3rd box: iden. prop= m+0=m
4th box: Zero prop: m x 0=0
(x+2)(x+8) = x^2 +10x +16
(x^2 + 10x + 16)(x-1) = x^3+9x^2+6x-16, so the other dimension is x-1
