The length of a small ant is 3\cdot 10^{-3}3⋅10 −3
meter and the length of a large ant is 3.5\cdot 10^{-2}3.5⋅10
−2
meter.



a.) Find the difference in length, in millimeters, of the two ants.

Write your answer in scientific notation.

If there is a trail of 2 small ants and 1 large ant in a straight line, find the total length of the line. Write your answer in scientific notation.

step-by-step explanation:

the first option i believe

step-by-step explanation:

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
