Answer:
C
Step-by-step explanation:
We see that we can factor out 2x from the equation! So our equation becomes 2x(x-2) = 0.
Since the only way for things to multiply to equal to zero is if at least one of the numbers is 0.
So if x-2 is the 0, then x = 2.
If 2x is the 0, then x = 0.
So our answer is C. 0,2
Write that as 7x. Writing it as x7 could lead to confusion. 7*x would be OK.
Answer:
21
Step-by-step explanation:
30 - 9 +3
30 - 12
18
18 - 12=4
12/4 = -3
18 - -3
21
Log (x) = 3
10^3 = x
x = 1,000
