Yes they are if that helps, if you still are unsure than just mesure them and you will see
3x^2+11x-4=10x-1
3x^2+11x-10x-4+1=0
3x^2+x-3=0
Δ=1^1-4*3*(-3)=1+36=37
x1=(-1+V37)/6
x2=( -1-V37)/6
Answer:
38

Step-by-step explanation:
Let the number of cups of onions Katrina still needs to chop = x
She has already chopped the onions =
cups ≈
cups
So total amount of chopped onions =
cups
Since, onion soup recipe calls for the chopped onions =
cups ≈
cups
Therefore, equation which shows the number of cups of onions to be chopped more will be,

We further solve this equation for the value of x,
x = 
x = 
=
cups
≈
cups
