If f(x) = 3x and g(x) = 7x-1, what is (fog)(4)?

83

Step-by-step explanation:

solution:

we have

f(x)= 3x & g(x)= 7x-1

now

fog= f{g(x)}

or, f(7x-1)

or, 7.3x-1 = 21x-1

so, fog(4)= 21*4-1=84-1=83

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

12
