4. Which of the following can be used
JulsSmile [24]

The option that can be used to support the idea that the set of polynomials is closed under multiplication is; Option C: (10x^(0.5) - 8)(5x^(0.5) + 4)

<h3>What is the Closure property under multiplication?</h3>

When multiplying polynomials, the variables' exponents are added, according to the rules of exponents. It is pertinent to note that the exponents in polynomials are whole numbers. The whole numbers are closed under addition, which guarantees that the new exponents will be whole numbers. Thus, we can also say that the polynomials are closed under multiplication.

Now, looking at the options, we can say that option C is the only polynomial that is closed under multiplication because its' variables and exponents will not change;

(10x^(0.5) - 8)(5x^(0.5) + 4)

The output will retain the same thing.

Solve the equation 4(3-2x)=22
jeka94
<span>4(3-2x)=22
4(3) - 4(2x) = 22
12 - 8x = 22
8x = 12 - 22
8x = -10
x = -10/8 = -5/4 
or
x = -1.25</span>

A man bought an article for #50,000, and sold it for #35,000. what is the percentage lost
Lyrx [107]

Answer:

30%

Step-by-step explanation:

Percentage loss is calculated as

\frac{loss}{original} × 100%

loss = 50000 - 35000 = 15000, thus

percent loss = \frac{15000}{50000} × 100% = 30%
