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.
Answer:
867 tickets were sold because if you divide how much they earned by how much it cost you get 867
If this is a problem about the Pythagorean theorem, maybe this helps! If the length of the ladder is 10 feet (C) and the base is 9 feet (B), you have to multiply each number by 2, add the total of both numbers and then round the number to the nearest hundreths ( use the radical button on your calculator) and there you have it , you will have the answer on your calculator. I hope this helps ;-)
