(x-12)(x-12) would factor to x²-24x+144.
(x-12)(x+12) = x²+144
Option C is correct :)
Since the photo booth charges a $500 fee for two hours at the party and an additional 50 dollars per hour, we have:
50x+500=C
Where x is the hours stayed and C is the total cost. Since Cindy doesn't want to spend more than 700 dollars, we have:

Explanation:
the mean, first of all, is the average. so, you need to find the average between 2 ans 4 since it has the same label. 2+4=6. 6/2=3
Answer: 3a
When you are doing distributive property, it can only happen if a number or exponent is before the bracket. From this equation, you can solve for x like so:
7(x+5)-x=42
7x+35-x=42 -Using distributive property (Multiplication)
6x=7 -Collecting like terms.
x= 7/6 -The answer.
Therefore x would equate to 7/6.
