2/3(x)-(-1/3(x)-4)=?
?=0
1÷3 = 0.3
2/3(x) - 0 -1/3(x) = ?
? = 0
2 ÷ 3 =.67
4(3)/ 3
your "x" becomes a negative
So, (-x) - 12 / 3 - 2/3(x)
we get the "12" from multiplying 4(3) from each other
Your like term of this problem▶ -x + 12
2(x) - (-x) - 12 / 3
3(x) + 12
x + 4 = 0
-4 -4
---- ----
4x - 4
4x - 4 = 0
We have one solution to this equation
So, therefore your answer for this question is:
x = -4
Answer:
130⁰. unsure. angle sum, 25+25+x =180, so x=180-25-25
Answer:
d
Step-by-step explanation:
f(x)-g(x)=2x²+4x-6-[2x²+2x+8]=2x²+4x-6-2x²-2x-8=2x-14
If you're referring to the different sets of real numbers, it's the ones that you could try to do subtraction and not get an answer that still in that set.
For example, natural numbers (aka 1, 2, 3, 4, ...) are not, because 7 - 11 = -4 and -4 is not a natural number.
Also, whole numbers (aka 0, 1, 2, 3, 4, ...) has the same issue.
Basically any set of real numbers that doesn't include negative numbers will have this issue.
