. ayo be g Write an equation that represents the word problem.
A wooden railing is 82 m long. It is to be divided into four pieces. Three pieces
will be the same length, and the fourth piece will be 2 m longer than each of the
other three. Find the length of each piece.

hope that helps that you're correct answer

Step-by-step explanation:

let each piece be x, and the fourth piece x+2:

3x + x +2 = 82

4x = 80

x = 20

3 pieces will be 20m each and the 4th will be 20+2 = 22m long

the car was traveling 40 mph before it started skidding. ( 2 points ) 17. was the driver were her brakes working at 75% efficiency or better? ( 2 points ) yes 29.

step-by-step explanation:

let's call the solutions x₁ = (5 - 2√7)/3 and x₂ = (5 + 2√7)/3

then the equation is (x-x₁)(x-x₂) = 0

if you fill that in you get a lot of numbers which you can recognize as ax²+bx+c=0.

step-by-step explanation:

you can see that a=1 (there is just an x²)

b = (-5 -2√7 + 2√7 - 5)/3 = -10/3

c = -2√7)/3 ) * (-5+2√7)/3) = -1/3

so your answer is 3x^2 – 10x – 1 = 0
