Answer is 12 to your question
Answer with explanation:
Time taken by a person to read number of pages in a chapter= 18 minutes
It is not given what is the length of the page.So,we can't say exactly how many pages can a person read by completely understading what is written in each page in a chapter.
So, to fully understand each and every page in 18 minutes you can read minimum number of pages from the option given.
Option A:⇒ 15, is most appropriate.

Answer:
464
Step-by-step explanation:
Answer:
Terms must have the same variable (letter) and the same exponent (little number)
(7x² +3y+ 5) +(9x²+11y- 2)
Opening bracket
7x²+3y+5+9x²+11y-2
keeping like terms together
7x²+9x²+3y+11y+5-2
Since terms having same variable and exponent can be subtracted, added,divided and multiplied
So
Solving like terms we get
<u>16x²+14y+3</u> which is a correct answer.
