Write an algebraic expression to represent each description.
let the variable n represent the number in each case.
simplify the expression, where applicable.

a) half a number
b) three less than double a number
c) the sum of three consecutive whole numbers
d) 76% of a number

answerthe vertex form

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

the radius is 2 times the diameter.
