Y=ax^2 +bx+c
y=a(x+3)(x+9)(x+20)

Are these quartic or quadratic and why?

The degree of a polynom is given by the highest power of x.

For second degree (quadratic) we have x²: so ax²+bx+c is quadratic

For quartic: we would have x⁴. None of them quartic.

For y=a(x+3)(x+9)(x+20), by expanding we get an x³. So this is cubic, or of third degree.

man its nopq i just guessed and got it right so uhh

step-by-step explanation:

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
