Answer:
see below
Step-by-step explanation:
a) 2(x - 1) = 4 (x + 2)
Distribute
2x-2 = 4x+8
Subtract 2x from each side
2x-2x-2 = 4x-2x +8
-2 = 2x+8
Subtract 8 from each side
-2-8 = 2x+8-8
-10=2x
Divide each side by 2
-10/2 = 2x/2
-5 =x
b)(3 - x) (x + 2) = 0
We can use the zero product property
3-x = 0 x+2= 0
3-x+x=0+x x+2-2=0-2
3=x x=-2
10 and 4 ------B.)
10 and 6-------C.)
10 and 8-------A.)
Hope this helps!
Answer:
C Multiply/divide both sides by the same non-zero constant
Step-by-step explanation:
Given
![A:\ 3(x + 2) = 18](https://tex.z-dn.net/?f=A%3A%5C%203%28x%20%2B%202%29%20%3D%2018)
![B:\ x + 2 = 6](https://tex.z-dn.net/?f=B%3A%5C%20x%20%2B%202%20%3D%206)

How to get B from A
It can be seen that B is a factor of A.
And to get B from A, all you need to do is divide both sides of A by 3.
i.e.
![\frac{3(x+2)}{3} = \frac{18}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B3%28x%2B2%29%7D%7B3%7D%20%3D%20%5Cfrac%7B18%7D%7B3%7D)
![x+2 = 6](https://tex.z-dn.net/?f=x%2B2%20%3D%206)
Hence, from the list of given options.
<em>Option C answers the question because 3 is a non zero constant and both sides of the equation were divided by 3</em>
Answer:
Step-by-step explanation:
she should move the decimal point 3 digits back and she will get a whole number of 8714
another way u can get the answer is by counting the zeros and go back that amount of u want to make the number bigger or count the zeros,and mover that many spaces so that the number will get smaller
