The side length of square is given as 2.5.
So, the perimeter if square will be :
Once the side is doubled, means new dimension of side of square will be :
So the new perimeter will be :
The original perimeter is 10.
The new perimeter is 20.
It means the perimeter is twice the original perimeter. : Answer D

If there are 18 people, then 12 of them are athletes.
If there are 3 athletes, then there are 12 musicians.
The number of musicians is 3 times the number of athletes
Answer: The answer is (D) The number of musicians is 3 times the number of athletes.
Step-by-step explanation: Given that the ratio of musicians to athletes in a school is 3 : 1. We are to select the correct statement out of the given four options.
Since the total number of people are not given, so we cannot say that 13 of them are musicians. Therefore, option (A) is incorrect.
If there are 18 people, then number of athletes is given by
and hence the option (B) is not correct.
If there are 3 athletes, then
x=3, and so the number of musicians = 3 × 3 = 9 ≠ 12. Therefore, the option (C) is not correct.
Number of musicians = 3x = 3 × x = 3 × number of athletes.
Thus, the correct option is (D) The number of musicians is 3 times the number of athletes.
3x + y = 12

2y-4
Answer:
x - 2 => x = 2
x² + 3ax - 2a
=> 2² + 3 × a × 2 - 2 × a
=> 4 + 6a - 2a
=> 4 + 4a
=> 4 ( 1 + a )
★ 1 + a = 0
a = -1
25x^5/5x^2
You need to divide 25 by 5 and subtract the exponent
5x³
