The length of the hypotenuse is??
yawa3891 [41]

Answer:

x = 14.31

Step-by-step explanation:

According to PYTHAGORAS Theorem,

let the Hypotenuse be x

{6}^{2}  +  {13}^{2}  =  {x}^{2}  \\ 36 + 169 =  {x}^{2}  \\ 205 =   {x}^{2}   \\  \sqrt{205}  = x \\ x = 14.31

PLEASE HELP 30 POINTS AND BRANILEST
LUCKY_DIMON [66]

Answer:

Go through the explanation you should be able to solve them

Step-by-step explanation:

How do you know a difference of two square;

Let's consider the example below;

x^2 - 9 = ( x+ 3)( x-3); this is a difference of two square because 9 is a perfect square.

Let's consider another example,

2x^2 - 18

If we divide through by 2 we have:

2x^2/2 -18 /2 = x^2 - 9 ; which is a perfect square as shown above

Let's take another example;

x^6 - 64

The above expression is the same as;

(x^3)^2 -( 8)^2= (x^3 + 8) (x^3 -8); this is a difference of 2 square.

Let's take another example

a^5 - y^6 ; a^5 - (y ^3)^2

We cannot simplify a^5 as we did for y^6; hence the expression is not a perfect square

Lastly let's consider

a^4 - b^4 we can simplify it as (a^2)^2 - (b^2)^2 ; which is a perfect square because it evaluates to

(a^2 + b^2) ( a^2 - b^2)
