Answer:
19
Step-by-step explanation:
If t = 7
Then 5 + 2t would be equal to
5 + (2*7)
5 + 14
19
The markup is the percent of the original price that it is increased by. To determine the percentage marked up, you will subtract the new price and the original price, and then divide that by the original price.
200-125=$75
75/200=0.375 or 37.5% markup.
First join the log4 on the left:
log4( x*(x-3) = log4(-7x+21)
Then x = -7, works: -7*(-10)=70 = -7*(-7)+21
x=-3, 18 = 42, does not work
x=3 0=0 works,
However, when one puts x = -7 in the *original* exression, log4(-7) or log4(-10) do not exist (you know why?). So x= -7 is extraneous.
Now x=3 gives log4(0) on the left and right, which does not exist.
So, C is the answer, both are extraneous. Seem to work but indeed don't work in the *original* equation
Answer: 
Concept:
Here, we need to know the power of imaginary numbers
i = √(-1)
i² = -1
i³ = -i
i⁴ = 1
