Janae wrote the following polynomial expression: 2x5 - 4x3 + 6x8.
Janae claimed it was a trinomial with a leading coefficient of 2.
Justin argued back claiming that it was a trinomial with a leading
coefficient of 6. Who is correct? Explain.

Justin is correct

Step-by-step explanation:

2x^5 - 4x^3 + 6x^8.

We need to rewrite the polynomial in decreasing order

6x^8 +2x^5 -4x^3

The leading coefficient is 6

1gm = 1000mg so 0.1gm = 1000mg

first, convert the weight to kg

160lb * 1kg/2.2lb = 72.7kg

next, the dose

72.7kg * 100mg/kg = 7270mg
