The standard form:
We have:
<em>multiply both sides by 2</em>
<em>add x to both sides</em>
Answer:
-4=x
Step-by-step explanation:
1) 1-2x=-x-3 (letter's to the left)
2) then you get 1-x=-3
3) then you subtract 1 on both sides
4) then you dived the -1
5)answer -4=x
Answer:
Whenever you assume values, try and make them as accurate as possible i.e. I am looking for consecutive even numbers so I will assume the values to be (2n - 2), 2n and (2n + 2)
s2−r2−q2=(2n+2)2−(2n)2−(2n−2)2s2−r2−q2=(2n+2)2−(2n)2−(2n−2)2
You get: 4n (4 - n)
So the solution must have 4 as a factor, which we see all options do.
To get -20, n(4-n) must be (-5). It will happen when n = 5.
To get 0, n = 0
To get 12, n(4-n) must be 3. It will happen when n = 3
To get 16, n(4-n) must be 4. It will happen when n = 2
There is no way n(4-n) could be 2 if n is an integer so 8 is not possible.Step-by-step explanation:
10 of the power of 3 equals 1,000. 10•10•10 = 1000
