Three examples of when negative numbers are used in daily life are...

1) Measuring weight--Finding out an amount of weight lost over the course of a fitness program

<span>2) Measuring income--Let's say if someone's income had a 20% decrease, then you could say "Mary-Sue's income over the year had an overall of a -20% growth."</span>

3) In golf--below par

4) (This is an extra if you don't like one of the other examples) Sea depth, and temperatures.

HOPE THIS HELPED!!! :-0 :-) ;-) <3 <3

Which polynomial represents twice the sum of -5x^2-x+6 and 7x^2+x-1?
elena-14-01-66 [18.8K]

The polynomial that represent twice the sum of -5x^{2} - x +6 and 7x^{2} + x -1 is : 4x^{2}+10

<h3>What is a polynomial?</h3>

A polynomial is any  algebraic expression that has the least value of the power of  its variable as 2.

When the highest value of the polynomial is 2, it is a called a quadratic expression.

Analysis:

2( -5x^{2} -x +6 + 7x^{2} +x -1)

2( 2x^{2} + 5) =

4x^{2} + 10

In conclusion, the polynomial that represents the above  expressions is 4x^{2} + 10
