If x-1 is a natural number then the next natural number is x-1 +1= X Which is the next natural number What is (x-1) * (X+1). A, b,c are any three consecutive natural number write the relationship between the product of a and c and the square of b.

See below.

Step-by-step explanation:

The next natural number is x+1.

( x - 1)(x + 1) = x^2 - 1.

Let a = x-1, b = x and c = x+1 ( as they are consecutive numbers).

Product of a and c = ac = x^2 - 1 (as above).

b^2 = x^2.

so ac = x^2 - 1 = b^2 - 1

ac = b^2 - 1

40 x 50 = 2000

step-by-step explanation:

simplifying

5(x + -6) = 2(x + 3)

reorder the terms:

5(-6 + x) = 2(x + 3)

(-6 * 5 + x * 5) = 2(x + 3)

(-30 + 5x) = 2(x + 3)

reorder the terms:

-30 + 5x = 2(3 + x)

-30 + 5x = (3 * 2 + x * 2)

-30 + 5x = (6 + 2x)

solving

-30 + 5x = 6 + 2x

solving for variable 'x'.

move all terms containing x to the left, all other terms to the right.

add '-2x' to each side of the equation.

-30 + 5x + -2x = 6 + 2x + -2x

combine like terms: 5x + -2x = 3x

-30 + 3x = 6 + 2x + -2x

combine like terms: 2x + -2x = 0

-30 + 3x = 6 + 0

-30 + 3x = 6

add '30' to each side of the equation.

-30 + 30 + 3x = 6 + 30

combine like terms: -30 + 30 = 0

0 + 3x = 6 + 30

3x = 6 + 30

combine like terms: 6 + 30 = 36

3x = 36

divide each side by '3'.

x = 12

simplifying

x = 12
