Answer:
The width of the prism is 2 cm
Step-by-step explanation:
The given parameters are;
The volume of the prism = 170 cm³
The length of the prism = 5 cm
The height of the prism = 17 cm
The volume of the prism is given by the relationship v = Length, l × Height, h × Width, w
Therefore;
The volume of the prism = 5 cm × 17 cm × w = 170 cm³
Which gives;
w = 170 cm³/(5 cm × 17 cm) = 170 cm³/(85 cm) = 2 cm
∴ The width of the prism = 2 cm.
The answer to 4 would be one because negative times negative times negative equals negative.
The answer to 5 would be 62.5. This is because 5 to the third power is 125. 125 x 4 = 500. Then 5 + 3 = 8, so you would divide 500 by 8 and get 62.5.
I hope this helped you. Comment if you have any questions. :)
If those are your roots, in factorization form they are [x-(-1+i)][x-(-1-i)], which simplifies to (x+1-i)(x+1+i). FOIL that out like you would anything else to get the mess that looks like this:
. Putting things in order makes it easier to deal with.
. Canceling out what we can, gives us
.
. That simplifies to
, which of course gives us
and
is the final result. Your missing term there is 2x
6 3/4 pieces, but if you just want a whole number then 6
