Answer:

k = - 12.56 or k = 0.56

Step-by-step explanation:

Given

k² + 12k = 7

To complete the square

add ( half the coefficient of the k- term )² to both sides

k² + 2(6)k + 36 = 7 + 36, that is

(k + 6)² = 43 ( take the square root of both sides )

k + 6 = ± \sqrt{43} ( subtract 6 from both sides )

k = - 6 ± \sqrt{43}, thus

k = - 6 - \sqrt{43} ≈ - 12.56 or k = - 6 + \sqrt{43} ≈ 0.56

The sum of two consecutive natural numbers is 525.<br> Find the numbers.
Luda [366]

Answer:

262 and 263 are consecutive natural numbers whose sum is 525.

Step-by-step explanation:

Natural number are a subset of real numbers consisting in positive integers (i.e. 1, 2, 3, 525) and two natural numbers are consecutive when distance between each other is equal to 1. (|x-y| = 1, \forall\,x,y \in \mathbb{N}) We can interpret the statement mathematically by means of the following expression:

x + y = 525

x = n

y = n+1

Where x, y, n \in \mathbb{N}.

This system is reduced to a single equation and solved afterwards:

n +(n+1) = 525

2\cdot n + 1 = 525

2\cdot n = 524

n = 262

Now we evaluate x and y to obtain the natural numbers:

x = 262

y = 263

262 and 263 are consecutive natural numbers whose sum is 525.
