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

yes, gavin is right.

step-by-step explanation:

gavin is correct. 

this problem is about converting 9% per year to how many percent per quarter. the rate is still the same. it only differed in the time period. so, through dimensional analysis,

9% per year  × (1 year / 4 quarters) = 2.25% per quarter

if he was asked to convert 9% per year to how many percent per quarter  compounded quarterly, then you will not simply divide by four. this is because compounding is not linear.

hope this , have a good day. c;
