Step-by-step explanation:
13.8% = 0.138 in decimal form.
Percent means 'per 100'. So, 13.8% means 13.8 per 100 or simply 13.8/100.
If you divide 13.8 by 100, you'll get 0.138 (a decimal number). Read more below on this webpage.
As you can see, to convert from percent to decimal just divide the percent value (13.8) by 100, and remove the "%" sign.

Answer:
C) (a-12b)(a+12b)
Step-by-step explanation:
a^2-144b^2 = (a-12b)(a+12b)
This is the formula that when two terms squared are written with a minus sign between them their factors are the product of the original numbers once with a plus sign and once with the minus sign.
This can be explained by multiplying them.
(a-12b)
<u> *(a+12b) </u>
a²- 12ab
<u> +12ab - 144b² </u>
<u> a² +0 - 144b² </u>
We see we get the same answer as applying the formula above.
