Answer:
$39
Step-by-step explanation:
To calculate the total cost of his meal, add the subtotal ($30), the tax on subtotal ($30 X 10%) and the tip ($30 X 20%).
Convert all percentages to decimals to multiply.
Finding tax:
10% = 0.1
Tax = $30 X 0.1 = $3
Finding tip:
20% = 0.2
Tip = $30 X 0.2 = $6
Subtotal + Tax + Tip
= $30 + $3 + $6
= $39
The total cost of his meal was $39.

Answer:
The polynomial is 
Step-by-step explanation:
∵ The polynomial of dgree 4 has 3 , 1 and zero as a double root
∴ x = 3 , x = 1 , x = 0 , x = 0
∴ The factors of this polynomials are:
(x - 3) , (x - 1) , (x) , (x)
∴The polynomial = (x)(x)(x - 3) (x - 1)
∴ The polynomial =
