We have .
First let us factor the 2 to obtain,
We can now see clearly that the expression inside the parentheses is a difference of two squares.
We now write the 4 as 2². So that we obtain the expression,
Recall that
Hence our expression becomes,
Therefore, when factored completely,
Volume of prism B=800*6³/8³
=800*27/64
=25*27/2
=575/2
=287.5 cm³
Answer:
The answer would be D. 5
Step-by-step explanation:
X = 30 because the ratio of 27/45 = .6 so 18/.6 is 30
7 x 2 = 14
3 x 1 = 3
14+3 = 17
answer 17 unit^2
