W=-5 because you distribute at the beginning with the 2 variables and you solve that's equation and you will end up with 6w divided by 30 and that's will give u W=-5
Substitute the value of b = -2 to the expression
![-4b-8+(-1)-b^2+2b^3=2b^3-b^2-4b-8-1=2b^3-b^2-4b-9\\\\2(-2)^3-(-2)^2-4(-2)-9=2(-8)-4+8-9=-16-4+8-9=-21](https://tex.z-dn.net/?f=-4b-8%2B%28-1%29-b%5E2%2B2b%5E3%3D2b%5E3-b%5E2-4b-8-1%3D2b%5E3-b%5E2-4b-9%5C%5C%5C%5C2%28-2%29%5E3-%28-2%29%5E2-4%28-2%29-9%3D2%28-8%29-4%2B8-9%3D-16-4%2B8-9%3D-21)
