Помогите пж,,, 40+b* 50+b сравнить не вычисляя обьяснить

Answer 1

50+b больше чем 40+b

Answer 2

50 больше 40 вот и объяснение

Answer 3

40b + 50b can be simplified by combining like terms. In this case, the like terms are the terms with the variable "b". When you combine 40b and 50b, you simply add the coefficients (40 and 50) together to get 90b. So, 40b + 50b = 90b.

This can be explained using the distributive property of multiplication over addition. When you have a common factor (in this case, "b") in two terms being added together, you can factor out that common factor and then add the coefficients of the terms. In this case, factoring out "b" from 40b and 50b gives you b(40 + 50), and then adding the coefficients inside the parentheses gives you 90b.

So, when you compare 40b and 50b without actually calculating them, you can simply say that 40b + 50b = 90b.
