I got it correct
Answer:
(f·g)(x) = x³ -8x² +20x -16
Step-by-step explanation:
The distributive property is useful for this.
(f·g)(x) = f(x)·g(x) = (x² -6x +8)(x -2)
= x(x² -6x +8) -2(x² -6x +8)
= x³ -6x² +8x -2x² +12x -16
(f·g)(x) = x³ -8x² +20x -16

<em>Additional comment</em>
I find it convenient to separate the terms of the shortest polynomial. That way, the distributive property doesn't need to be used quite so many times. Of course, any outside minus sign applies to all terms inside parentheses.
Answer:
Step-by-step explanation:
b/c these are similar triangle we can say this ratio of the two triangles is true
15/x = 31/(44+x)
now just use algebra to solve for x
15*(44+x) = 31x
660+15x = 31x
660=16x
41.25 =x
41.3 looks good
