Answer:
1/9 is smaller than 1/6, so it takes more amounts of 1/9 to make make a fraction equal to 1/3
Answer:
(4n+5)² - 9 = 4 ( 4n² + 4 + 2n)
since, we have a factor 4 common from the expression
therefore, we can say that for any natural n the value of the expression (4n+5)^2–9 is divisible by 4.
Step-by-step explanation:
Data provided in the question:
Expression : (4n+5)² - 9
To prove: for any natural n the value of the expression (4n+5)² - 9 is divisible by 4.
Now,
This can be proved if there is on factor of 4 that can be taken from the expression
Thus,
solving the expression
(4n+5)² - 9
= [ (4n)² + 5² + 2 × 4n × 5 ] - 9 [because ( a + b )² = a² + b² + 2ab]
or
= 16n² + 25 + 8n - 9
or
= 16n² + 16 + 8n
now taking 4 common from the above expression, we get
= 4 ( 4n² + 4 + 2n)
since, we have a factor 4 common from the expression
therefore, we can say that for any natural n the value of the expression (4n+5)^2–9 is divisible by 4.

Step-by-step explanation:
Can u give options
they all multiple by 4 like y 2/4+ 4y- 21
Answer: 17 1/6 or 17-18
(u guess which is right if its an integer ^^)
Step-by-step explanation:
25 3/4 ÷ 1 1/2
First change the mixed fractions to improper fractions.
<u>25 3/4 </u>= <u>103/4</u>
<u>1 1/2 </u>= <u>3/2</u>
Now divide: 103/4 ÷ 3/2
103/4 * 2/3 (multiply by flipping the second fraction)
= 206/12
Now divide: 206 ÷ 12
= 17 2/12 (<u>simplified:</u> 17 1/6)
<u><em>The answer will be 17 1/6 </em></u> (OR 17-18)
