A store has 4 bins of planet posters with 23 posters In each bin. It has 3 bins of planet calendars with 26 calendars in each bin yesterday 72 calendars were sold how many planet posters and calendars are left in all? Explain how you found your answer and how you know if your answer is reasonable

lol we need to see what the question is asking about

step-by-step explanation:

you can't solve x because it is 2 linear equation and you only have one equation

b if for most of the graph

d if y intercept

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
