Anumber is four times larger than the square of half the number

Step-by-step explanation:

Let the number = x

Read carefully the sentence part beginning with 4 times larger

4* something

4 times larger than the square of 1/2 the number

4 * (x/2)^2

4*(x/2)^2 = x

4*x^2/4 = x

x^2 = x  be very careful how you handle this. It looks like 0 might be an answer, but it isn't. If you divide x on both sides and you allow 0, you will get 0 / 0 and that is undefined. You must exclude that possibility with some sort of statement.

x cannot be 0.

x^2/x= x/x

x = 1

-2

7 - 9 = -2

reversed:

-2 + 9 = 7

the answer is:

mean: 6

mad: 2.14
