When using the Quadratic Formula, how can you tell when a quadratic equation has only one solution/one x-intercept? When the discriminant (b2 - 4ac) is negative

When b in the quadratic formula is greater than the discriminant (b2 - 4ac).

When the discriminant (b2 - 4ac) equals zero

When the discriminant (b2 - 4ac) is not a perfect square

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

cause it equals more
