The atom's place on the table is determined solely by its number of protons
- A periodic table is a table containing different elements and arranged across the periods and groups of the table.
- The elements in a periodic table are numbered and arranged based on their atomic number.
Since the atomic number is equal to the number of protons an element contains, hence we can conclude that <u>the atom's place on the table is determined solely by its </u><u>number of protons</u>

Step-by-step explanation:
Answer:
C. 437 mm^2
Step-by-step explanation:
Area = 1/2bh
A = 1/2(38*23)
A = 437
We can factor the equation using grouping.
![(x^3+x^2) + (x + 1)](https://tex.z-dn.net/?f=%28x%5E3%2Bx%5E2%29%20%2B%20%28x%20%2B%201%29)
Factor both halves of the equation.
![x^2(x+1) + 1(x+1)](https://tex.z-dn.net/?f=x%5E2%28x%2B1%29%20%2B%201%28x%2B1%29)
Both groups have a factor of (x+1). We can use the distributive property to find the other factor. That is, ac + bc = (a+b)(c).
So our final factored form is:
![(x^2+1)(x+1)](https://tex.z-dn.net/?f=%28x%5E2%2B1%29%28x%2B1%29)
Now let's find the roots of the equation. These are the x values where the graph crosses the x axis. To do this, set both factors equal to zero and solve for x.
![x^2+1=0](https://tex.z-dn.net/?f=x%5E2%2B1%3D0)
![x^2 = -1](https://tex.z-dn.net/?f=x%5E2%20%3D%20-1)
![x = \sqrt{-1}](https://tex.z-dn.net/?f=x%20%3D%20%20%5Csqrt%7B-1%7D%20)
This factor does not produce any rational roots because taking the square root of a negative number results in a complex number.
![x+1=0](https://tex.z-dn.net/?f=x%2B1%3D0)
![x=-1](https://tex.z-dn.net/?f=x%3D-1)
So the equation hass one root of x = -1. This means that the graph should cross the x axis at x = -1. Therefore the last picture is the correct graph. Hope this helps!
Answer:
x= 3/8 or 0.375
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
7x+−12=3x+1
Step 2: Subtract 3x from both sides.
7x+−12−3x=3x+1−3x
4x+−12=1
Step 3: Add 1/2 to both sides.
4x+−12+12=1+12
4x=32
Step 4: Divide both sides by 4.
4x4=324
x=38
