The answer would be x=0, 2i, -2i
Answer:
K 20
Step-by-step explanation:
f(x) = 7x2 - 4x
f (2) = 7 (2)^2 - 4(2)
= 28 - 8
= 20
Since they replaced the x inside f(x) with 2, just do that the same to the right side, change all x into 2

You got divide só see mean, the middle number is the median, range you add all number and divide but how many number has
Answer: In the hundreds place.
Step-by-step explanation:
1. You know that the first number has a 7 in its tenths place. This means that it is after the decimal point. You can write is as following:
x.7
Where x represents the other digits.
2. The second number has a 7 with a value that is 1,000 times greater than the value of the 7 in the first number, this means that you can know the place of the 7 in the second number if you multiply the first number by 1,000, or in other words, move the decimal point three places to the rigth. Therefore:
x.7*1000=7xx
3. As you can see, the 7 is in the hundred place in the second number.
