Evaluate the expression for u = –0.4 and v = –9. Write your answer as a decimal or whole number. –2uv = _____

Identify Expression: Identify the expression to be evaluated. The expression given is –2uv. We need to substitute u = –0.4 and v = –9 into this expression.Substitute Values: Substitute the values of u and v into the expression. Substitute u = –0.4 and v = –9 into –2uv to get –2 * (–0.4) * (–9).Perform Multiplication: Perform the multiplication. First, multiply –2 by –0.4 to get 0.8. Then, multiply 0.8 by –9. Calculation: 0.8 * –9 = –7.2Check Result: Check the result. The multiplication is correct, and the result is a decimal number as requested.

-2uv =

_____

Identify Expression: Identify the expression to be evaluated. $\newline$ The expression given is $-2uv$ . We need to substitute $u = -0.4$ and $v = -9$ into this expression.
Substitute Values: Substitute the values of $u$ and $v$ into the expression. $\newline$ Substitute $u = -0.4$ and $v = -9$ into $-2uv$ to get $-2 \times (-0.4) \times (-9)$ .
Perform Multiplication: Perform the multiplication. $\newline$ First, multiply $-2$ by $-0.4$ to get $0.8$ . Then, multiply $0.8$ by $-9$ . $\newline$ Calculation: $0.8 \times -9 = -7.2$
Check Result: Check the result. $\newline$ The multiplication is correct, and the result is a decimal number as requested.
