Use the quadratic formula to solve the equation. -2x^2 - 5x + 5 = 0

.

Step-by-step explanation:

The Quadratic Formula for a second degree polynomial is a formula for the values of its solution i.e. for finding the values of x.

It is given by, .

Now, we have the given quadratic equation ,

which gives a = -2 , b = -5 , c = 5.

Substituting the value of a, b , c in the above formula, we get

.

.

.

Hence, the solution of the given quadratic equation is .

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

definitely a. the others have almost all data points on one side of the line.
