Answer:
i know 1st one is b
dont know 2nd one
Step-by-step explanation:
The coefficient does not determine whether a function is a polynomial or not but the degree of the polynomial.
Multiplying polynomial expressions
Given the following product of the polynomial as shown below
10x^4 * 0.5x^3
Multiply the decimal and the exponent to have;
10x^4 * 0.5x^3
(10*0.5) *(x^4 * x^3)
(10*1/2) * (x^4+3)
(5)x^7
Hence the product of the given polynomial function is 5x^7
The error in Han's thinking is by assuming 0.5x^3 is not a polynomial because 0.5 is not an integer. The coefficient does not determine whether a function is a polynomial or not but the degree of the polynomial.

Answer:
Step-by-step explanation:
23*(34-18)÷18
23*16÷18
23*8/9
184/9
20.44
use BODMAS rule (Bracket Of Multiplication Addition Subtraction)
A) Sale value = 48
Profit on the total cost = 20% = 0.20
=> Total cost + 0.20 total cost = Sale value
=> 1.20 total cost = 48
=> total cost = 48 / 1.20
=> total cost = 40
B) Cost of the gloves = 4
=> Cost of the skirt = total cost - cost of the gloves
=> Cost of the skirt = 40 - 4 = 36
C) Price of the skirt = total value - price of the gloves
Total value = 48
Price of the gloves = cost of the gloves + margin
margin of the gloves = 100% on the cost = cost
Price of the gloves = cost of the gloves * 2
Price of the gloves = 4 * 2 = 8
=> Price of the skirt = 48 - 8 = 40
D) Profit on the skirt = price of the skirt / cost of the skirt = 40 / 36 = 1.1111
Profit % = 11,11 %
