Пошаговое объяснение: -9(4b+8)-(3+b)+3(8b+60)=-36b-72-3-b+24b+180= =-13b+105

Answer 2

-13b-72-3-b+24+180=-14b+129

Answer 3

To simplify the expression, follow the order of operations (PEMDAS/BODMAS):

P: Parentheses first, E: Exponents (none in this expression), MD: Multiplication and Division (from left to right), AS: Addition and Subtraction (from left to right).

Let's simplify the expression step by step:

1. Start with the parentheses: -9(4b + 8) - (3 + b) + 3(8 + 60)

Apply the distributive property to the terms within the parentheses:

-9 * 4b = -36b -9 * 8 = -72 3 * 8 = 24 3 * 60 = 180

The expression becomes:

-36b - 72 - (3 + b) + 24 + 180

2. Simplify the inner parentheses: -36b - 72 - (3 + b) + 24 + 180

Add the terms inside the second set of parentheses:

-36b - 72 - 3 - b + 24 + 180

3. Combine like terms: -36b - b = -37b -72 - 3 = -75

The expression becomes:

-37b - 75 + 24 + 180

4. Continue to combine like terms:

-37b + 105

So, the simplified expression is:

-37b + 105
