Answer:

Explanation is below.

Step-by-step explanation:

Commutative property:

The Commutative property states that order does not matter. Multiplication and addition are commutative.

For example 2+5=5+2 .

Associative property:

The associative property states that you can add or multiply regardless of how the numbers are grouped.

For example 2x(7x5)=(2x7)x5

Distributive property:

The distributive property lets you multiply a sum by multiplying each addend separately and then add the products.

For example 2(x+y)=2x+2y

Zero property of addition:

Zero is the additive identity. Adding zero to a number will not change its value. a + 0 = a.

For example 2z + 0 = 2z

Identity property of multiplication:

Property is that multiplying any number by 1 allows the number to keep its identity.

For example 14 x 1 = 14

Additive inverse:

The additive inverse of a number a is the number that, when added to a, yields zero. This number is also known as the opposite, sign change, and negation.

For example 13 + -13 = 0

The sum of two numbers is eighteen. The total of three times the smaller and twice the larger is forty-four. Find the two number
sashaice [31]

Answer:

  • The numbers are 8 and 10.

Step-by-step explanation:

Let the numbers be x and y.

The sum of two numbers is eighteen:

  • x + y = 18

The total of three times the smaller and twice the larger is forty-four:

  • 3x + 2y = 44

Solve the system by substitution:

  • x = 18 - y

Substitute x and solve for y:

  • 3(18 - y) + 2y = 44
  • 54- 3y + 2y = 44
  • 54 - y = 44
  • y = 54 - 44
  • y = 10

Find x:

  • x = 18 - 10
  • x = 8

Factories 24x^2-41x+12
andriy [413]

Answer:

(3x - 4)(8x - 3)

Step-by-step explanation:

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

product = 24 × 12 and sum = - 41

The required factors are - 32 and - 9

Use these factors to split the x- term

24x² - 32x - 9x + 12 ( factor the first/second and third/fourth terms )

= 8x(3x - 4) - 3(3x - 4) ← factor out (3x - 4) from each term

= (3x - 4)(8x - 3) ← in factored form
