The sum of the roots of the equation x^2+ x= 2 is:
-1
1
0

-1.

Step-by-step explanation:

x^2 + x - 2 = 0

The sum of roots of

ax^2 + bx + c = 0 is -b/a

So comparing the above with the given equation this sum is -1/1 = -1.

the smallest possible measurement of the width is 14 feet

step-by-step explanation:

let's assume length of parallelogram is 'l'

width of parallelogram is 'w'

the perimeter of a parallelogram must be no less than 40 feet

so, we get

we are given

length of parallelogram is 6 feet

so,

l=6

we can plug it

now, we can solve for w

subtract both sides by 12

divide both sides by 2

and we get

so,

the smallest possible measurement of the width is 14 feet
