09 Jun 2021

Evaluate the following expressions for x = 2.

-9.2(4 – x)
-9.2(4 – (2))
-9.2(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 :)
