F(x) = (3x-5)(4x+2) is the function linear or quadratic ?

f(x)=(3x-5)(4x+2) is a quardatic function.

Step-by-step explanation:

f(x)=(3x-5)(4x+2)

simplify

f(x)=3x(4x+2)-5(4x+2)

f(x)=

adding the coefficients of x, we get

f(x)=

which is quardatic equation since it contains the terms 12.

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
