whatsz 4(x+5.1)-5x
It is an algebraic expression.
To simplify the algebraic expression 4(x + 5.1) - 5x, let's follow the order of operations (PEMDAS/BODMAS) which states that you should solve parentheses first, then exponents, then multiplication and division (from left to right), and finally addition and subtraction (from left to right).
1. Distribute the 4 to each term inside the parentheses:
4(x + 5.1) - 5x = 4x + (4 * 5.1) - 5x
2. Multiply:
4x + (4 * 5.1) - 5x = 4x + 20.4 - 5x
3. Combine like terms:
4x - 5x + 20.4 = (-x) + 20.4
Therefore, the simplified form of the expression 4(x + 5.1) - 5x is -x + 20.4.
