Expand the polynomials and simplify.(0.2x–0.5y)^2

The simplify and expanded form of the polynomial is :

Step-by-step explanation:

Since we have given that

As we know the formula

So, we will apply this,

Here,

a = 0.2x

b = 0.5y

So, it becomes,

Hence, the simplify and expanded form of the polynomial is :

hi how are you doing today? if you ever need just tell me

step-by-step explanation:

1 mph

step-by-step explanation:

if the question is asking how much does she drive per mile then,
