<span>f(x)=3x+8 and g(x)=6x+6

(f + g)(x) = f(x) + g(x)
 
              = </span>3x+8 + (6x + 6) = 3x + 6x + 8 + 6 = 9x + 14<span>

</span>(f + g)(x) = <span> 9x + 14
</span>
(f + g)(-1) = <span> 9*-1 + 14 = -9 + 14 = 5
</span>
<span>(f + g)(-1) = 5</span>

Robert has a container in the shape of a cube with an edge length of 6.1 cm. What is the volume of the container?
Setler79 [48]
Since it's a cube all the side lengths are the same. So the calculation would be 6.1x6.1x6.1 or 6.1^3
V=226.981cm^3
V=Length x width x height
