Answer:
(-1)(-1)(-1)
(-1)(-1)(-1)(-1)(-1)
These, since they are all negatives and there are an odd number of terms.
Step-by-step explanation:
x^3-10x^2=27x-18=0 has no solutions
x^3-10x^2-27x-18=0 has 3 solutions
x^3-10x^2-27x-18=0 also has three solutions
3x + 4x +5x = 54 (because the perimeter = sum of its dies)
12x = 54
x = 4.5
So the 3 sides are 3*4.5 , 4*4.5 and 5*4.5
= 13.5, 18 and 22.5 units (answer)
