Answer:
The closet equivalent of the ratio of 'a' to 'c' is:

Step-by-step explanation:
Given
i.e.
a=0.63x
i.e.
c=3/8x
Hence,


Thus, the closet equivalent of the ratio of 'a' to 'c' is:

The model is is I think 25 mentally
12. <span>
13. 24
14. 3 sqrt 7</span>
To solve this, you distribute the -y to both terms, 2 and 4y.
It will look something like this: (2*-y)+(4y*-y)
When you simplify, look for any like terms that can be combined, and if none, then leave it as it is.
Your final answer will be: -2y-4y^2
X^3+2x^2-2x-4 remainder -32/X-2
