São Paulo is not built on an island. It is located inland in Brazil, on the Southeastern plateau.

To simplify the expression -15 + 4(6b + 9) - 8a, follow these steps:

Step 1: Simplify the expression inside the parentheses.
Multiply 4 by each term inside the parentheses:
-15 + 24b + 36 - 8a

Step 2: Combine like terms.
Combine the terms with b: -15 + 24b.
The expression becomes:
24b - 15 + 36 - 8a

Step 3: Continue combining like terms (if possible).
Combine -15 and 36: -15 + 36 = 21.
The expression becomes:
24b + 21 - 8a

Therefore, the simplified expression is:
24b + 21 - 8a.

To simplify the expression -15 + 4(6b + 9) - 8a, we can follow the order of operations (also known as PEMDAS) to simplify it step by step.

Step 1: Simplify the expression inside the parentheses.
-15 + 4(6b + 9) - 8a becomes -15 + 4(6b) + 4(9) - 8a.

Step 2: Multiply the coefficients outside the parentheses by the terms inside the parentheses.
-15 + 4(6b) + 4(9) - 8a becomes -15 + 24b + 36 - 8a.

Step 3: Combine like terms.
-15 + 24b + 36 - 8a becomes (24b - 8a) - 15 + 36.

Step 4: Simplify the constants.
(24b - 8a) - 15 + 36 becomes 24b - 8a - 15 + 36.

Step 5: Combine like terms.
24b - 8a - 15 + 36 becomes 24b - 8a + 21.

Therefore, the simplified form of -15 + 4(6b + 9) - 8a is 24b - 8a + 21.
