Answer:
x = -3
Step-by-step explanation:
3x + 9 = 12x + 36 (rewrite)
3x - 12x + 9 = 36 ------> 3x - 12x = 36 - 9
3x - 12x = 36 - 9 (collect like terms)
-9x = 36 - 9 ( substract)
-9x = 27 (divide both sides for the answer)
-9 -9
x = -3

Because the absence of corners allows more space for more balls
Answer:
The correct answer is h = 3.
Step-by-step explanation:
To solve this problem, we should first use the distributive property on the left side of the equation. This means that we can multiply each of the terms inside the parentheses by -2 (be careful that you distribute the negative as well). This is modeled below:
5h - 2(11 - h) = h - 4
5h - 22 + 2h = h - 4
Next, we can combine like terms on the left side of the equation.
7h - 22 = h - 4
Now, we can subtract h from both sides of the equation to move all of the variable terms to the left side of the equation.
6h - 22 = - 4
Next, we can add 22 to both sides of the equation to isolate the variable term on the left side of the equation.
6h = 18
Finally, we can divide both sides by 6 in order to get the variable completely isolated.
h = 3
Therefore, the correct answer is h = 3.
Hope this helps!
Answer:
Rewrite equation as:
x^2 + 2x +2 =0
a = 1 b = 2 c = 2
x = (-b +- sqr root (b^2 -4ac)) / 2a
x = (-2 +- sqr root (2^2 - 4*1*2) ) / 2
x = (-2 +- sqr root (4 - 8) ) / 2
x = (-2 + sqr root (-4) ) / 2
x = -1 +- i
