The values of a, b, and c in the equation x² + 6x - 55 = 0 are:

The following are the answers:

a = 1

b = 6

c = -55

Step-by-step explanation:

When looking for a, b, and c in a quadratic, you are looking at coefficients only. The coefficient of x^2, which in this case is 1, is a. The coefficient of x, which in this case is 6, is b. Lastly, the constant at the end, which in this case is -55, is c.

b

step-by-step explanation:

a difference is the result of subtraction. while each of these expressions has subtraction in it, a difference will be the result when subtraction is the last operation applied in the order of operations for the expression. this means subtraction must be outside of the parenthesis. only b has this.

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
