Answer:
B) 
Step-by-step explanation:
We want to simplify ![\sqrt[3]{-125n^{12}}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B-125n%5E%7B12%7D%7D)
![\sqrt[3]{-125n^{12}} = \sqrt[3]{-1 * - 1 * -1 * 5 * 5 * 5 * n^4 * n^4 * n^4} \\\\= \sqrt[3]{(-1)^3 * 5^3 * (n^4)^3}\\\\= -1 * 5 * n^4\\\\= -5n^4](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B-125n%5E%7B12%7D%7D%20%3D%20%5Csqrt%5B3%5D%7B-1%20%2A%20-%201%20%2A%20-1%20%2A%205%20%2A%205%20%2A%205%20%2A%20n%5E4%20%2A%20n%5E4%20%2A%20n%5E4%7D%20%5C%5C%5C%5C%3D%20%5Csqrt%5B3%5D%7B%28-1%29%5E3%20%2A%205%5E3%20%2A%20%28n%5E4%29%5E3%7D%5C%5C%5C%5C%3D%20-1%20%2A%205%20%2A%20n%5E4%5C%5C%5C%5C%3D%20-5n%5E4)
The answer is 
The fraction of the total books about mammals is 7/18
Let the total number of books in the school be 1 whole , ie 12/12( since we are dealing with fractions)
Number of science books =7/12
Number of mammals books =2/3 of science books
=2/3 x 7/12=14/36 = 7/18
Since the total books are 12/12 which is also =1 whole
Then the fraction of total books that are about mammals are 7/18 x 1 whole =7/18

Since 1 and 2 are congruent and formed by AD and BC respectively, and are in alternate interior positions, AD and BC are parallel ny the alternate interior angle theorem. AED and DEC equal 180 and so do DEC and CEB, so DEC equals CEB. this means triangle ADE is similar to triangle BEC by AA, so this means angle ADE equals angle CBE. then similar to angles 1 and 2 DC and AB are parallel. then by definition of a parallelogram, the figure is a parallelogram. since it is made of two pairs of parallel line segments
