What is the simplest form of the expression below? 2x2 ? 10x ? 28 6x × 6 x ? 7

X

Step-by-step explanation:For this case you must simplify the expression respecting the rules of multiplication of mathematics.

 The steps to simplify the expression are the following:

 First multiply what is in the parentheses

 -2x ^ 2 (x - 5) + x (2x ^ 2 - 10x) + x

 -2x ^ 3 + 10x ^ 2 + 2x ^ 3 - 10x ^ 2 + x

 Then add the terms that have the same exponent

 (-2x ^ 3 + 2x ^ 3) + (10x ^ 2 - 10x ^ 2) + x

 x

 The final simplification is

 x

 answer

 x

since proposition states that a number is greater than 25, if is true then the number must actually be greater than 25.

this implies that all possible options, except 24, can be accepted

-2

7 - 9 = -2

reversed:

-2 + 9 = 7
