-k + 0.03 + 1.01k = -2.45 - 1.81k
Multiplying through by 100, we have
-100k + 3 + 101k = -245 - 181k
2/7 = x/10
cross multiply:
10 * 2 = 20
7 * x = 7x
7x = 20
x = 2.857

Answer:
b=4 makes the equation a perfect square.
Step-by-step explanation:
As long as you factorize out the equation, you'll get a result of (x+2)^2. This multiplied using foil gives you, x^2 + 2x + 4. Making it a perfect square. You could also have -2 = b which makes a perfect square, but that's not in the options.
