Answer 2

Заполнение пропусков, применяя распределительный закон:

# А) (25 + 78) * 4 = … + …

To apply the distributive law, we need to distribute the multiplication operation to both terms inside the parentheses: = (25 * 4) + (78 * 4) = 100 + 312 = 412

Therefore, the missing values in the equation are 100 and 312.

# Б) 47 * 8 + 53 * 8 = … * (… + …)

We can also apply the distributive law here by distributing the multiplication operation to both terms inside the parentheses: = (47 + 53) * 8 = 100 * 8 = 800

Therefore, the missing values in the equation are 100 and 800.

# В) (15 + 71) * … = … * 12 + 71 * …

To apply the distributive law, we need to distribute the multiplication operation to both terms inside the parentheses: = 86 * … = … * 12 + 71 * …

Since we have two missing values, we cannot determine their exact values without additional information.

# Г) 18 * ….. = … * 75 + … * 93

To apply the distributive law, we need to distribute the multiplication operation to both terms on the right side of the equation: = 18 * ….. = (… * 75) + (… * 93)

Again, since we have two missing values, we cannot determine their exact values without additional information.

# Д) 8 * (54 + 125) = …… + ……

To apply the distributive law, we need to distribute the multiplication operation to both terms inside the parentheses: = (8 * 54) + (8 * 125) = 432 + 1000 = 1432

Therefore, the missing values in the equation are 432 and 1000.

# Е) 14 * 62 + 14 * 18 = … * (… + …)

We can apply the distributive law here by distributing the multiplication operation to both terms inside the parentheses: = 14 * (62 + 18) = 14 * 80 = 1120

Therefore, the missing values in the equation are 14 and 80.

# Ж) …… * 13 = 23 * … - 16 * …

To apply the distributive law, we need to distribute the multiplication operation to both terms on the right side of the equation: = (23 * …) - (16 * …) = 23 * … - 16 * …

Again, since we have two missing values, we cannot determine their exact values without additional information.
