use a graph and a table to solve the equation. round to the nearest thousandth if necessary x2 – 7x - 5 = 1/2x - 4

The nearest thousand is 6,0000Step-by-step explanation:

sum

Step-by-step explanation:

We know that, 'multiplication of two or more quantities can be expressed as the SUM of the same quantities'.

This means that 'multiplication of two or more terms is equal to adding as many copies of one of them'.

i.e. a × b = a + a + ( 'b' number of times ) = b + b + ... ( 'a' number of times )

Let us consider few examples,

A.  2 × 4 = 8

So, we can have that,  

2 × 4 = 2 + 2 + 2 + 2 = 8 i.e. we add the number 2 four times.

2 × 4 =  4 + 4 = 8 i.e. we add the number 4 two times.

B. 3 × 7 = 21

3 × 7 = 3 + 3 + 3 + 3 + 3 + 3 + 3 = 21 i.e. we add the number 3 seven times.

3 × 7 = 7 + 7 + 7 = 21 i.e. we add the number 7 three times.

Hence, 'The multiplication of two or more quantities may be expressed as the SUM of the same quantities'.
