I think the answer is x=10
Answer:
x = 2 + √3 and
x = 2 - √3
Step-by-step explanation:
Please use " ^ " to denote exponentiation: x^2 - 4x + 1 = 0.
Here you have multiple choices of methods of solution:
quadratic formula, completing the square, graphing, and so on.
If we complete the square, then: x^2 - 4x + 1 = 0 becomes
x^2 - 4x + 4 - 4 + 1 = 0, or
(x - 2)^2 = 3
Taking the square root of both sides, we get x - 2 = ±√3, so that the roots are:
x = 2 + √3 and
x = 2 - √3
Answer:
D
Step-by-step explanation:
sqrt(7) = about 2.6
and that divided by 2 is
0.8 which means D is the Answer
Answer:
The answer will be A because you start at 4 and in between 4 and 5 you will go up to 7 and that will be your answer
