Question

СРОЧНО! Примените распределительное свойство умножения: а) 11x(60+a); б) 21х(38-b); в) (х-9)х24; г) (у+4)х38. P.S.: Если нужно, я пример решения могу скинуть в комментарии.

Answer 1

А)11*(60+2)
б)21*(38-3)
в)(30-9)*24
г)(8+4)*38

Answer 2

Applying the Distributive Property of Multiplication

The distributive property of multiplication states that for any three numbers a, b, and c, the product of a and the sum of b and c is equal to the sum of the products of a and b, and a and c. In other words:

a x (b + c) = (a x b) + (a x c)

Let's apply the distributive property to the given expressions:

a) 11 x (60 + a) Applying the distributive property, we can expand this expression as: 11 x 60 + 11 x a The result is 660 + 11a.

b) 21 x (38 - b) Expanding this expression using the distributive property, we get: 21 x 38 - 21 x b The result is 798 - 21b.

c) (x - 9) x 24 Using the distributive property, we can expand this expression as: x x 24 - 9 x 24 The result is 24x - 216.

d) (y + 4) x 38 Expanding this expression using the distributive property, we get: y x 38 + 4 x 38 The result is 38y + 152.

I hope this helps! If you have any further questions, feel free to ask.
