To find the value of x, we need to use Pythagorean Theorum.
The equation for Pythagorean Theorum is a^2 + b^2 = c^2.
C^2 is our hypotenuse, or the side that's across from the right angle.
13 is our hypotenuse, and 12 is b.
Since our numbers are not squared, let's square them.
13 x 13 = 169
12 x 12 = 144.
Our equation now is a^2 + 144 = 169
To find a^2, we need to subtract b^2 from c^2. 
Subtract 144 from 169.
169 - 144 = 25.
a^2 = 25
Square root both sides.
a = 5.
x = 5.
I hope this helps!

Step-by-step explanation:

Let y^2-5y+1 =A

Required polynomial=B

A-B=5

B=A-5

B=y^2-5y+1 -5

B=y^2-5y-4

Hence,Required polynomial=y^2-5y-4

If n is prime number then 2n-1 is prime also?​
BlackZzzverrR [31]

Answer:

Step-by-step explanation:

Prime numbers are number that can only be divided by itself and 1.

E.g 2,3,5,7,11,13,17,19,23,29 etc.

So, note that this sequence doesn't have a pattern, it is neither Geometry Progression nor Arithmetic Progression.

Now, let take look at the model given

If n is prime, then 2n-1 is prime

Let take 5 for

n=5 is a prime number

2n-1=2(5)-1=10-1=9

9 is not a prime number so the model doesn't work

A prime number doesn't have sequence so, it cannot be model with sequence.

I hope this help

If the slope of a line is 4/5, does the line rise (from left to right), fall (from left to right), horizontal or vertical?
slava [35]

slope: 4/5 is a positive slope

  • positive slopes rises from left to right
  • positive slopes falls from right to left
  • neither horizontal or vertical.

The picture below shows some examples of <u>equation with positive slope</u>.
