please answer it only if you know it even if it is only one answer but it should be correct it is really important.​

Answer 1

Answer:

The given equation is in the form of the Distributive Law of Multiplication over Addition.

= a × (b + c) = (a × b) + (a × c)

Let, a = -48, b = 26, c = -36

26 × (−48) + (−48) × (−36)

= (−48) × 26 + (−48) × (−36) (b × a = a × b)

= (−48) [26 − 36] (a × b + a × c) = a (b + c)

= (−48) × (−10) [∵ (- × – = +)

= 480

Answer

26 × (– 48) + (– 48) × (–36)=480
