When solving the equation –3a2 = 7a – 3 using the quadratic formula, what values should be used for a, b, and c?
Question 7 options:

a = –3, b = 7, and c = –3

a = –3, b = –7, and c = 3

a = 3, b = 7, and c = 3

a = 3, b = –7, and c = –3

a = -3, b = -7 and c = 3

Step-by-step explanation:

–3a2 = 7a – 3 must be re-written in standard form:

–3a2 - 7a + 3 = 0

Then a = -3, b = -7 and c = 3 (third answer choice)

a = -3, b = -7, and c = 3

Step-by-step explanation:

–3a² = 7a – 3

-3a² - 7a + 3 = 0

a = -3, b = -7, c = 3

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
