William rests a 12 foot ladder against a wall. The bottom of the ladder rest 7 feet from the base of the wall. If the window is a 9 feet will the ladder reach the window? Will the ladder reach at least 9 feet up the wall? Explain. Approximately how high up the will the ladder reach (round to the tenth) U need help pl

i would need to see the dot plot : )

ur right ive taken the test

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

d would equal 12
