Evaluate the following expressions for x = 2.
-9.2(4 – (2))
-9.2(2)
Evaluate the following expression for x = 2.
-36.8 + 9.2x What are the values of the expressions when x = 2?Answer:
-9.2(4 - 2) = -18.4
-36.8 + 9.2*2 = -18.4
Explanation:
Given:
-9.2(4 - x)
-36.8 + 9.2x
Required:
Evaluate when x = 2
-9.2(4 - x)
Substitute 2 for x
-9.2(4 - x) = -9.2(4 - 2)
Evaluate the expression in the bracket
-9.2(4 - x) = -9.2(2)
Remove the bracket
-9.2(4 - x) = -9.2*2
-9.2(4 - x) = -18.4
-36.8 + 9.2x
Substitute 2 for x
-36.8 + 9.2x = -36.8 + 9.2 * 2
-36.8 + 9.2x = -36.8 + 18.4
-36.8 + 9.2x = -18.4
What are the final values of the expressions? -18.4 and -18.4 Explanation: Hope this helped :)
