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 is the value of x in the triangle?
yulyashka [42]
<h3>Answer: C) x = 13</h3>

====================================================

Work Shown:

We have a right triangle with legs a = 5 and b = 12. The hypotenuse is c = x which is unknown for now.

Use the pythagorean theorem to find x.

a^2 + b^2 = c^2

5^2 + 12^2 = x^2

25 + 144 = x^2

169 = x^2

x^2 = 169

x = sqrt(169)  .... apply the square root to both sides

x = 13

Find the quotient and express it in the simplest form
pychu [463]
2i(4+5i)(4-5i) =82i
4+i nothing more can be done it is at simplest form 

so \frac{82i}{4+i} = \frac{82}{17} + \frac{328}{17} i

so your answer is  \frac{82}{17} + \frac{328}{17} i
