The solution to the polynomial expression since the power of the variable is in the second degree is 6.29 × 10² cm
<h3>What is the power of a variable?</h3>
The power of a variable refers to the exponent of the variable and the highest power of a variable is the degree to which the variable is being raised. From the information given, the highest power of the variable is a polynomial.
Given that:

So, since the exponents are in the same power we are going to add them all together multiplied by their exponent.
i.e.

I am also pretty sure the answer is B, but give the answer above me Brainliest. Have a great day
Answer:
50 g
Explanation:
d= m/v
rearranging the above equation
m = d x v
m = 2.5 g x 20 g/cm3
m = 50 g
Answer:
Explanation:
The glass rod losses electrons because the silk cloth has a positive charge so it attracts the negative charge of the glass rod.
Mass number is the mass number of that particular Element found in the periodic table and the atomic number is the atomic no. Again found in the periodic table
