Adrianna runs up 4.5 flights of stairs. How far will Arianna have to run down to represent an additive inverse?

She needs to run down 4.5 flights of stairs to represent an additive inverse

Step-by-step explanation:

Having an additive inverse means that she will be back at point zero.

The point zero in this context simply refer to her starting point.

So if she has run up 4.5 flights of stairs, then to be back at her starting point, she needs to run down also 4.5 flights of stairs

there are many solutions.

step-by-step explanation:

step 1: simplify both sides of the equation.

4x+6=4x^2+10x−4

step 2: subtract 4x^2+10x-4 from both sides.

4x+6−(4x^2+10x−4)=4x^2+10x−4−(4x^2+10x−4)

−4x^2−6x+10=0

step 3: factor left side of equation.

−2(2x+5)(x−1)=0

step 4: set factors equal to 0.

x=-5/2 or x=1
