Answer:-12
Step-by-step explanation:
-18
1) Distribute the -6 to the parentheses
-4 - (6*7) - (-6*3)
2) Simplify
-4 - 42 + 18
-18
For this case we must simplify the following expression:

We have that by definition of properties of powers that is fulfilled:

Then, rewriting the expression:

Answer:

Answer:
9
Step-by-step explanation:
Substitute w = 3 into the expression
6w - 9
= 6(3) - 9
= 18 - 9
= 9
The x-coord. of the vertex is halfway between the given zeros. Here, it'd be halfway between x=3 and x=9, which comes out to x = 6 (answer).
