Answer 2

Step-by-step explanation:

Sure, I can help you with that.

**Expression:** 3x²–(4x–7)

**Value of x:** -8

**Solution:**

* First, we need to simplify the expression inside the parentheses.

* 4x – 7 = 4(-8) – 7 = -32 – 7 = -39

* Now, we can rewrite the expression as follows:

* 3x² – (4x – 7) = 3x² – 39

* Finally, we can substitute the value of x into the expression and evaluate.

* 3x² – 39 = 3(-8)² – 39 = 3(64) – 39 = 192 – 39 = 153

Therefore, the value of the expression 3x²–(4x–7) when x = –8 is 153.
