Answer:
(x + 1)(x + 9) = 0
Step-by-step explanation:
After you subtract 16 from both sides, you get ...
x² +10x +9 = 0
When you factor this equation, it becomes ...
(x +1)(x +9) = 0
_____
For the zero product property to be of any use, the form of the equation must be a product that equals zero.
___
<em>Comment on the other answer choice</em>
(x -1)(x -9) = 0 = x² -10x +9 . . . . . the x term is different from that in the given equation. It has the wrong sign.

Step-by-step explanation:
10 + 24 divided by 276
5.924 g
Step-by-step explanation:
The average weight of a boron atom is 10.811 atomic mass units (AMU). Therefore 3.3 x 10^23 atoms of boron will weight;
3.3 x 10^23 * 10.811 = 3.56763 x 10 ^ 24
One (1) gram = 6.022 x 1023 AMU. Therefore to convert AMU to grams;
3.56763 x 10 ^ 24 / 6.022 x 10^23
= 5.924 g

Answer:
The height of each story is 10 ft
Step-by-step explanation:
see the attached figure to better understand the problem
Let
x -----> the height of each story
The linear equation that represent this problem is
![26=x+x+6](https://tex.z-dn.net/?f=26%3Dx%2Bx%2B6)
Solve for x
Combine like terms
![26=2x+6](https://tex.z-dn.net/?f=26%3D2x%2B6)
Subtract 6 both sides
![26-6=2x](https://tex.z-dn.net/?f=26-6%3D2x)
![20=2x](https://tex.z-dn.net/?f=20%3D2x)
Divide by 2 both sides
![20/2=x](https://tex.z-dn.net/?f=20%2F2%3Dx)
Rewrite
![x=10\ ft](https://tex.z-dn.net/?f=x%3D10%5C%20ft)
therefore
The height of each story is 10 ft
