The stress distribution on a structure is given by s = 2x^2+ 4x - 30 where s is stress in pounds per square inch and x is the distance in feet from a reference point. At what distance is the stress equal
to 0 pounds per square inch?

it's both, now can you answer my most recent question?

the square root of what number? if you add that, then someone will probably answer the question.

step-by-step explanation:

hello :

by applying the distributive property :

6 × 4.3 = 6 × ( 4 + 0.3 )

            =   (6 ×   4) + (6 ×   0.3)

            = 24 + 1.8

6 × 4.3 = 25.8
