We can make equations and start filling in what we already know, assuming $n$ is Niko's age, $L$ is Lila's age, $a$ is Amber's age, and $k$ is Kamerons age.

Our first equation:

n = 3L

We know that Niko is 45, so

45 = 3L

Divide both sides by 3:

L = 15

So, Lila is 15 years old.

Another equation:

n = L + 3a

We already know Niko and Lila's age:

45 = 15 + 3a

Subtract 15 from both sides:

30 = 3a

Divide both sides by 3:

a = 10

So Amber is 10 years old.

Another equation:

k = 2(a + L)

We know Amber and Lila's age:

k = 2(10 + 15)

k = 2(25)

k = 50

So Kameron is 50 years old.

Hope this helped!

A polynomial is every function that looks like this:
f(x)=(An)*xⁿ + (An-1)*xⁿ⁻¹ +.....+A₁*x +A₀

So functions that are polynomials are:

3x²-5x⁴+2x-12,
x⁵-5x⁴+4x³-3x²+2x-1,
x⁻⁵-5x⁻⁴+4x⁻³-3x⁻²-1,
x³-7x²+9x-5x⁴-20.

And functions that are NOT polynomials:

4/x⁴ + 3/x³ - 2/x² -1,
⁴√x - ³√x + ⁴√x - 8x +16.

So the second picture is correct.
