Question

1)- 8а· (- 15 b) = 120ab2) 11x· (-7 y) = -77xy

Answer 1

Ответ:

Пошаговое объяснение:

- 8а· (- 15 b) = 120ab

120аб = 120аб

аб = 120 : 120

аб = 1

11x· (-7 y) = -77xy

-77ху = -77ху

ху = -77 : -77

ху = 1

Answer 2

It looks like you have two algebraic equations that involve multiplying variables and numbers. Let's solve them one by one:

1. 8a * (-15b) = 120ab To solve this equation, you can use the distributive property of multiplication over addition or subtraction:

8a * (-15b) = -120ab

So, the solution to this equation is -120ab.

2. 11x * (-7y) = -77xy Again, you can use the distributive property to simplify this equation:

11x * (-7y) = -77xy

So, the solution to this equation is -77xy.

Both equations simplify to the given expressions, and these are the solutions to the equations.
