Answer:
(x+6)^2 =0
Step-by-step explanation:
x^2+ 12x + 36 = 0
Subtract 36 from each side
x^2+ 12x + 36-36 = 0-36
x^2 +12x = -36
Take the coefficient of x
12
Divide by 2
12/2 =6
Square it
6^2 =36
Add this to each side
x^2+ 12x + 36 = -36+36
(x+12/2)^2 = 0
(x+6)^2 =0

Answer:
Step-by-step explanation:Simplifying
2a + 6b = 100
Solving
2a + 6b = 100
Solving for variable 'a'.
Move all terms containing a to the left, all other terms to the right.
Add '-6b' to each side of the equation.
2a + 6b + -6b = 100 + -6b
Combine like terms: 6b + -6b = 0
2a + 0 = 100 + -6b
2a = 100 + -6b
Divide each side by '2'.
a = 50 + -3b
Simplifying
a = 50 + -3b
Answer:
13.1
Step-by-step explanation:
Finding mean in data set is finding the average. The way to find the average is by adding all the data in the set (the # of movies watched), then divide them by how many numbers are in the data set (7).
16+13+19+16+8+10+10=92
After you add the data in the set, you have to divide it by the pieces of data there is.
So 92/7=
13.1428571
<u />
If you round 13.142...to the nearest tenth, you get <u>13.1.</u>
