Solve this equation?

You can solve this equation by factoring.  To factor a quadratic, you need to find two numbers whose product is equal to the c term of the function (in this case-8) and whose sum is equal to the b term (6).  In this equation, the factors are 4 and 2 because:

4x2=8

4+2=6

The factored form of this equation is : (x+4)(x+2)=0

Now, you can solve for x by setting each term equal to 0.

x+4=0

x=-4

x+2=0

x=-2

A trick for this is to just flip the sign of the the number in the parentheses.

x={-4, -2}

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
