Why the multiple of any number other than 1 are not prime numbers

1 answer:

6 0

Because the fact that they can be the answer of a multiplication of a set of numbers other than one, means that they cannot be prime.

What is a prime number? A prime number is a number whose only factors are 1 and itself.

So for example, if you can use 2 multiplied 7 to get 14, then that means 2&7 are factors of 14. Since 14 has factors other than one and itself, then it isn't prime.

The value of the expression -2 xy for x = -4.7 and y = 0.2 is _____.

sergeinik [125]

The value of the expression -2xy for x = -4.7 and y = 0.2 is 1.88. Thus option number 3 is correct.

<u>Solution:</u>

We have been given an expression that is -2xy and have been asked to find its value for the given values of x and y

The given values of x and y are -4.7 and 0.2 respectively.

To find the value of the expression for the given values of x and y we substitute the values of x and y in the given expression and solve it as follows:

Given expression = -2xy

$\begin{array}{l}{=-2(-4.7)(0.2)} \\\\ {=9.4 \times 0.2} \\\\ {=1.88}\end{array}$

Hence the option number 3 is correct.

You lose one quarter, two dimes, and two nickels. Write the amount as a decimal.

lesya [120]

1 quarter = 0.25
2 dimes = 2(0.10) = 0.20
2 nickels = 2(0.05) = 0.10
for a total of : 0.25 + 0.20 + 0.10 = 0.55.....so u have lost 0.55
