The vertex form of the equation of a parabola is y= (x + 5)2 + 49.
what is the standard form of the equation?

y = x² + 10x + 74

Step-by-step explanation:

Given

y = (x + 5)² + 49 ← expand the factor using FOIL

  = x² + 10x + 25 + 49

  = x² + 10x + 74 ← in standard form

answer: i believe its b. if you sound out the sentences that sounds wrong.

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
