The square of the sum of two consecutive positive even integers is 4048 more than the sum of the squares of these two numbers. find the two numbers.

44 and 46.

Step-by-step explanation:

Let the 2  numbers be x and x + 2  ( because they are consecutive even numbers). So:

(x + (x + 2))^2 = 4048 + x^2 + (x + 2)^2

(2x + 2)^2  - x^2 - (x + 2)^2 = 4048

4x^2 + 8x + 4  - x^2 - (x^2 + 4x + 4)  = 4048

4x^2 - x^2 - x^2 + 8x - 4x + 4 - 4 = 4048

2x^2 + 4x - 4048 = 0

x^2 + 2x - 2024 = 0

(x - 44)(x + 46) = 0

x = 44 because we are given that it is positive.

Therefore the other number is x + 2 = 46.

option (b) is correct

step-by-step explanation:

to find the solution of this system, we need to convert it into reduced row-echelon form. we have,

after applying row operations r2 -> r2/2 and r3 -> r3/3, we get,
