In order to simplify this expression, we need to multiply the numeric values together and the variables together.
So we have:

Therefore the correct option is the third one.
Answer:
The second number after the decimal point- the 6
We'll check if they're orthogonal:
u*v=0
(6,-2)*(8,24)=0
6*8+(-2)*24=0
48-48=0
0=0
they are orthogonal vectors
Answer:
-17
Step-by-step explanation:
it's telling you to replace x with -3.
You have to replace all the x's with -3.
(-3)2 + (-3) - 8 = -17
