The distributive property states that:

a(b+c)=ab+bc.

or more generally: a(b+c+d)=ab+av+ad.



This is a very useful tool to perform multiplication.

For example, if we want to multiply 7 by 234, we can proceed as follows:

7*234=7(200+30+4)=7*200+7*30+7*4=1400+210+28=1610+28=1638


back to our problem,

4 * 24 = 4(20+4)=4*20+4*4=80+16=96  ($)

So, instead of multiplying 4 by 24, we multiplied 4 by 20 and 4, which is easier, and then added these together.


Answer:  

4 * 24 = 4(20+4)        [=4*20+4*4=80+16=96 ($)]

What are the zeros of f(x) = x^2 + x - 20?
kvv77 [185]
X² + x - 20
= (x+5)(x-4)

x + 5 = 0
x = -5

x - 4 = 0
x = 4

How to get x when x^3-x^2+x-1=0?
Art [367]

Answer:

x = 1 or x = ± i

Step-by-step explanation:

Note the sum of the coefficients

1 - 1 + 1 - 1 = 0

This indicates that x = 1 is a root, thus (x - 1) is a factor

Using long division or synthetic division, then

x³ - x² + x - 1 = (x - 1)(x² + 1), thus

(x - 1)(x² + 1) = 0

Equate each factor to zero and solve for x

x - 1 = 0 ⇒ x = 1

x² + 1 = 0 ⇒ x² = - 1 ⇒ x = ± \sqrt{-1} = ± i

A polynomial is factored using algebra tiles. Which polynomial was factored?
alexdok [17]

The algebra tiles shows the polynomial x² - 2x - 8

<h3>Polynomial</h3>

Polynomial is an expression that involves only the operations of <em>addition, subtraction, multiplication</em> of variables.

Algebra tiles are square and rectangle shaped tiles or tiles that represent numbers and variables.

From the image:

Polynomial = x² + x + x - x - x - x - 1 - 1 - 1 - 1 - 1 - 1 - 1 - 1 = x² - 2x - 8

The algebra tiles shows the polynomial x² - 2x - 8
