(1 point) an experiment consists of choosing a subset from a fixed number of objects where the arrangement/order of the chosen objects is not important. determine the size of the sample space when you choose the following: (a) 4 objects from 29 answer : (b) 2 objects from 10 answer : (c) 5 objects from 16 answer :

step-by-step explanation:

hans did not square the 40-unit side; he merely multiplied it by 2.   incorrect.

linear pair postulates

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
