3. An English teacher gives students 1 point for reading a magazine article, 5 points for reading a chapter of a book, and 20 points for completing an entire book. If Sue reads 4
magazine articles, 7 chapters, and completes 2 books this term, how many points will
she earn? Show or explain your work.

76%

step-by-step explanation:

24% are dogs and the remaining is 76% because 100-24=76

step-by-step explanation:

is their an equation anywhere i can take a   look at it and see if i am right.

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

yep b and c r the correct got it! : )
