Plss me also this how to answer this a quadratic equation there is 4 categories to put some answer standard forms and a set of a b and c me guys i need an answer before june 30 2019‍♀️‍♀️

see explanation

Step-by-step explanation:

The standard form of a quadratic equation is

ax² + bx + c = 0 : a ≠ 0

Express the equations in this form and extract the coefficients

1

4 - 2x + 3x² = 0 , that is

3x² - 2x + 4 = 0 ← in standard form

with a = 3, b = - 2 and c = 4

2

x(x + 5) - 2x = 0 ← distribute parenthesis

x² + 5x - 2x = 0

x² + 3x = 0 ← in standard form

with a = 1, b = 3 and c = 0

3

x² - 2x(x - 2) + 5 = 0 ← distribute parenthesis and simplify

x² - 2x² + 4x + 5 = 0

- x² + 4x + 5 = 0 ← in standard form

with a = - 1, b = 4 and c = 5

16

step-by-step explanation:

2 x 40 = 80

80/5

= 16

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
