Answer:
a is the right answer I calculated it
I think that’s good look , I’m not pretty sure
The two triangles are similar
3x / 20 = (4x + 2) / (20 + 8)
3x / 20 = (4x + 2) / 28
28 * 3x = 20 * (4x + 2)
84x = 80x + 40
4x = 40
x = 10
answer
x = 10
Hello! That is not true. 0.24 < 1414. 0.24 is a decimal that's less that 1 and 1414 is a whole number that is way greater than 1. 0.24 =/= 2,424. As just explained, 0.24 is less than one and 2,424 is way greater than one. Ming's statement is false.
The largest prime that needs to be checked for factors of a number n is floor(sqrt(n)), or |sqrt(n)| in some notations, meaning the largest integer that does not exceed sqrt(n).
For example, if checking 169, whose squre-root is 13. There will be NO prime factors below 13 (1 is not a prime). So check for all prime factors up to and including the largest prime equal to or less than sqrt(n).
