The table is missing though but you may consider the following calculations :
Y = 1.6 x
for x = 1 minutes
Y = 1.6 laps
for x = 2 minutes
Y = 3.2 laps
for x = 3 minutes
Y = 4.8 laps
The resulting equation of that step is the square root of (x + 2)² is (x + 2).
<h3>What is the square root function?</h3>
A square root function is defined as a one-to-one function that takes a positive number as an input and returns the square root of the given input number.
From there, it was pretty easy for Theo to find the solutions
to the original equation.
If (x + 2) = +2 , then x = 0 .
If (x + 2) = -2 , then x = -4
Hence, the resulting equation of that step is the square root of (x + 2)² is (x + 2).

Lets first numbers is x, second is (x+2), third is x+4
sum is x+(x+2)+(x+4)=87
3x+6=87
3x=81
x=27
Answer: smallest number is 27

Answer: −5<x<1
I’ll keep it simple for you so you can actually learn. “Bi” means two, everything that has two terms is a binomial. And the “tri” means three, so three terms. And well the one left monomial is one term.
Meaning 10xyz is one term, which means it’s a Monomial.
8x^2 + 0.25 two terms so binomial
