X(x+1) 1(x+4)
x^2+x+x+4
x^2+2x+4
68 meters is the correct answer
Hey there!
Palindromes are numbers that can be written the same way backwards, such as 101 and 12321. You're looking for some numbers which are palindromes, and so are their square numbers.
Alright, I'll give you four of those:
- 121 is a palindrome, and its square root is 11, both palindromes. 11 x 11 = 121
- 484 is a palindrome, and its square root is 22, both palindromes. 22 x 22 = 484
- 10201 is a palindrome, and its square root is 101, both palindromes. 101 x 101 = 10201
- 12321 is a palindrome, and its square root is 111, both palinromes. 111 x 111 = 12321
Hope this helps!
Result:
5
/5 : 1
/2 = 5
/5 · 2
/1 = 5 · 2
/5 · 1 = 10
/5 = 2
To divide one fraction by another, invert (turn upside-down) the second fraction, then multiply.
