1st. Find the pattern
Pattern is dividing by 2.
24/2=12
12/2=6
6/2=3
X^2 + 12x = -6
x^2 + 12 x + 6^2 = -6 + 6^2
(x + 6)^2 = - 6 + 36
(x +6)^2 = 30
In the first step I had to add 6^2 = 36. The answer is option B. 36.
Associative property and distributive property
50-10 = 40. 40 divided by 6 = around 6/7. So about 6/7 weeks
