Sav [38]

Answer:

$3385 per week

Step-by-step explanation:

so, he gets $370 plus 4.5% of what he is selling.

In a polynomials equation do you add the exponents if they are different
Alexus [3.1K]
You can only add exponents if you are multiplying two of the same variable together. For example,
x^{12} \times x^4 = x^{16}

You take them away if you are dividing.
<span>x^{12} \div x^4 = x^{8}

In a polynomial equation, you can add together two of the same variable if they have the same exponent
</span>3x^4 + 7x^4 = 10x^4

Or you can take them away in a similar fashion,
<span>3x^4 - 7x^4 = -4x^4

But you cannot add two (or more) different exponents,
</span>6+4x+7x^2 = 6+4x+7x^2 (it does not get any simpler)

I hope this has answered your question, if not, leave a comment and I'll update the answer.
