So start by putting the negative sign into the second polynomial.
-(6x^2-2x-9)
-6x^2+2x+9
then combine like terms with the first polynomial
5x^3+4x^2-6x^2-2x+9
and you will get
5x^3-2x^2+2x+9
Hope this helps you.

Step-by-step explanation:
Harvey is 3 times as old as Jane."
<span>h = 3j </span>
<span>"The sum of their ages is 48 years." </span>
<span>h + j = 48 </span>
<span>substitution </span>
<span>(3j) + j = 48 </span>
<span>4j = 48 </span>
<span>j = 12 </span>
<span>h = 3j = 36</span>

Answer:
_Area top_= √1/4(a+b+c)(b+c−a)(c+a−b)(a+b−c) + _Area bottom_ √1/4(a+b+c)(b+c−a)(c+a−b)(a+b−c)+ Area lateral =h(a+b+c)
1) Surface Area: 76,017.691
√V=1/4h(a+b+c)(b+c−a)(c+a−b)(a+b−c)
2) Volume: 631,332.519
Volume - given empty space
3) 631,332.519 - 335,954.96= 295,377.559
Percentage of 335,954.96 in 631,332.519=
