The answer is correct
but I think in step 2 that should read the Associative property
For x²+bx+c, to complete the square, you add (half of b)²
b=8 in this case, so you add 4², which is 16
x²+8x+16-16-4
y=(x+4)²-20 is the final form.

Answer:
-45.6 is the answer if you evaluate
Answer:
$63
Step-by-step explanation:
You have the constant, $45. You then receive $3 each week. This can be written at $45 + $3w, where w is the number of weeks. So in this case, we need to find out how much money you will have after 6 weeks. We just need to plug in 6 weeks into the equation. The new equation will now be $45 + $3(6).
3 times 6 is $18.
$45 + $18 will give you a final answer of $63.
