5. Use the lattice method to compute the following sum. B. 13 base four + 23 base four.
I just need B. I know the answer is 102 base four but I do not know the work in lattice method.

Answer is in the photo. I couldn't attach it here, but uploaded it to a file hosting. link below! Good Luck!

final total: 63

step-by-step explanation:

60 times sales tax

60 times 0.05

3

60 + 3

63

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
