0.6b + 3c
It is: 2a+5a = 7a when simplified
To simplify the expression (7a \cdot a), you multiply the coefficients and combine the like terms. The coefficient is 7, and (a \cdot a) is (a^2). Therefore, the simplified expression is (7a^2).
To simplify the expression -33 - 7a - 5, combine the constant terms (-33 and -5). This results in -38, leading to the simplified expression: -38 - 7a.
-7a-7b
7a
To simplify the expression ( 14ab^3 + 7a^{-2}b^{-1} ), we can express it with positive exponents. The term ( 7a^{-2}b^{-1} ) can be rewritten as ( \frac{7}{a^2b} ). So the expression becomes ( 14ab^3 + \frac{7}{a^2b} ). Since these two terms do not have a common factor, this is the simplest form of the expression.
The relevant expression is 7a.
The expression ( 7a - a - a - a - a ) simplifies by combining like terms. You can group the ( a ) terms together: ( 7a - 4a ), which results in ( 3a ). Therefore, the simplified expression is ( 3a ).
To simplify the expression (6(7a + 2b) + 8a - 8b), first distribute the 6: [6 \cdot 7a + 6 \cdot 2b = 42a + 12b.] Now, combine this with the remaining terms: [42a + 12b + 8a - 8b = (42a + 8a) + (12b - 8b) = 50a + 4b.] Thus, the simplified expression is (50a + 4b).

To simplify the expression 7a - 6, we combine like terms by adding or subtracting coefficients of terms with the same variables. In this case, there are no like terms to combine, so the expression remains as 7a - 6. It cannot be simplified further without additional context or information.
