Answer:

Commutative Property of Addition: a + b = b + a

Step-by-step explanation:

The Commutative Property of Addition implies that even on changing the order of addition the final result (i.e. the sum) remains the same.

  • Consider the addition of two numbers, say <em>a</em> and <em>b</em>:

a + b = b + a

Suppose <em>a</em> = 5 and <em>b</em> = 6, then:

<em>a</em> + <em>b</em> = 5 + 6 = 11

<em>b</em> + <em>a</em> = 6 + 5 = 11.

Thus, a + b = b + a.

  • Consider the addition of three numbers, say <em>a, b</em> and <em>c</em>:

a + b + c= a + c + b = b + a + c = c + a + b

Suppose <em>a</em> = 4, <em>b</em> = 3 and <em>c</em> = 6, then:

a + b + c = 4 + 3 + 6 = 13

a + c + b = 4 + 6 + 3 = 13

b + a + c = 3 + 4 + 6 = 13

c + a + b = 6 + 4 + 3 = 13.

Thus, a + b + c= a + c + b = b + a + c = c + a + b.

5х2-7x-6=0 <br><br> factored form
Vinvika [58]

Answer:

(x - 2)(5x + 3) = 0

Step-by-step explanation:

5x² - 7x - 6 = 0

Consider the factors of the product of the x² term and the constant term which sum to give the coefficient of the x- term.

product = 5 × - 6 = - 30 and sum = - 7

The factors are - 10 and + 3

Use these factors to split the x- term

5x² - 10x + 3x - 6 = 0 ( factor the first/second and third/fourth terms )

5x(x - 2) + 3(x - 2) = 0 ← factor out (x - 2) from each term

(x - 2)(5x - 3) = 0 ← in factored form
