Question

square any #, then double the result. Is your answer always sometimes or never greater then the result of doubling the #, then squaring it? justify your answer

Answer 1

The first situation is never greater than the second situation for all x except zero.

Answer 2

Sometimes greater. Is you square 0 and then double it you still get 0. Any other number would be greater because squaring a negative number makes it a positive.

Answer 3

if u were to square the number 2 u get 4 and u also get 4 if u double your number other than that the answer is always greater if u were to square it so i would have to say my answer would be sometimes

Answer 4

Sometimes. Essentially you're dealing with two functions, 2x^2 and (2x)^2, which is the same as 2x^2 and 4x^2. Since the square removes all negatives, the second one is twice as big for all numbers except 0, where it is the same.

Answer 5

well thats sometimes

if you pick 4 and square it that 16. then double it is 2.

if you pick 4 again and double it thats 8 and double it again is 16.

i'm not really sure whats your question though so i just answered by what i tihnk it is.

Answer 6

sometimes. re: fractions

3 squared x2 = 18

1/3 squared x2 = 2/9 (less than 3/9=1/3)

as a rule, it works less if and only if the number you're looking for, x, is greater than -1/2 but lesser than 1/2

youre welcome

Answer 7

Try 0

Answer 8

Ha ha! Not only does this punk have the guts to ask others to do her homework, she says 'justify your answer'- like we owe her something!

Answer 9

the latter is always greater for all integers.
2x^2 is less than (2x)^2.

Answer 10

always greater, because thats the answer
