Ursula mixed 3 1_ 8 cups of dry ingredients with 1 2_ 5 cups of liquid ingredients. For numbers 1a–1c, estimate the amount of ingredients Ursula used. Choose the correct benchmarks and sum. 1a. Ursula used about 2 3 3 1_ 2 4 cups of dry ingredients. 1b. Ursula used about 1 1 1_ 2 1 3_ 4 2 cup(s) of liquid ingredients. 1c. Ursula used about 3 3 1_ 2 4 4 1_ 2 cups of ingredients.

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

n word

step-by-step explanation:

what lives in the hood

4n=2m

ratio of m to n: 2/4 = 1/2
