One pretzel has 20 calories. Write an algebraic expression for the total number of calories in n pretzels. (so this doesn't get taken down) it's like people only get on here JUST to delete your post-

answer: 270

step-by-step explanation:

you have to times 200 by 1.35 to get your answer

i think u have 12 apples sorry again i don't really know if it correct i'm just tryna hrlp people out.

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
