The sides of a right triangle are x, x+21, and x+27. what is the length of the hypotenuse
mina [271]
Answer: 51 uinits

The three numbers are x , x + 21 and x + 27. 
The greatest of the 3 numbers is x + 27, so x + 27 has to be the hypotenuse.

----------------------------------------------
Pythagoras Theorem
----------------------------------------------

a² + b²  = c²

x² + (x+21)² = (x+27)²

x² + x² + 42x + 441 = x² + 54x + 729

x² - 12x -288 = 0

(x - 24)(x + 12) = 0

x = 24 or x = -12 (rejected, length cannot be negative)

----------------------------------------------
Find hypotenuse
----------------------------------------------
 Hypotenuse = x + 27 = 24 + 27 = 51 units

-----------------------------------------------
Answer: 51 units
----------------------------------------------

Find positive integers that satisfy
tankabanditka [31]

9514 1404 393

Answer:

  (x, y, z) = (1, 2, 3)

Step-by-step explanation:

The equations that result from reduction to row-echelon form are ...

  x = 0.4 +0.2t

  y = 5.6 -1.2t

  z = t

Then t must have a value 5n+3 for 0 ≤ n < 1. That is, t=3.

  x = 0.4 +0.2(3) = 1

  y = 5.6 -1.2(3) = 2

  z = 3

The integers that satisfy are (x, y, z) = (1, 2, 3).
