Remember that a positive number(+) multiplied by a negative(-) number results in a negative number. That means your answer will be negative. Also, dividing a positive number by a negative number and vice versa also results in a negative number.

Here is your equation:

4 \times -\frac{1}{4}

<h2><u>2 WAYS:</u></h2><h3>First Method:</h3>

Change -\frac{1}{4} into a decimal and multiply by 4.

First change -\frac{1}{4} into a decimal.

-\frac{1}{4} = -1 \div 4 = -0.25

Now multiply the decimal by 4.

-0.25 \times 4 = -1

Your answer is -1

<h3>Second Method:</h3>

Change 4 to a fraction and multiply.

4 \rightarrow \frac{4}{1}

Now multiply by -\frac{1}{4}:

\frac{4}{1} \times -\frac{1}{4}= \frac{-4}{4} \rightarrow -1

Your answer is -1

It doesn't matter which way you do it because you always end up with the same answer.

For all real numbers a and b, 2a • b = a2 + b2 Is this true or false? Explain why it false or true.
Andru [333]

Answer:

It's false.... correct is a2+2ab+b2

Step-by-step explanation:

This cannot be factored anymore although. when we try to substitute a with 5 and b with 2, the answer in the right hand side of the equation is -9.

That's why it's false.

The table can be used to determine the solution of equations, 2x − 2y = 6 and 4x + 4y = 28. A table with 6 columns and 2 rows. T
Alexus [3.1K]

The solution is (5,2)

Step-by-step explanation:

From the third column the equation for sum of equivalent system is given as;

8x = 40

divide both sides by 8 to get value of x

8x/8 = 40/8

x=5

Using the value of x in the fifth column's first equation will be;

4x +4y =28

4(5) + 4y =28

20 +4y =28

4y= 28-20

4y=8

divide both sides by 4 to get y

4y/4 =8/4

y=2

The solution is x=5 and y=2 written as (5,2)
