Answer:
2 or C
Step-by-step explanation:
I'm taking this to mean
4 = 2(x - 1)^2
4 = 2(x^2 - 2x + 1)
4 = 2x^2 - 4x + 2
2x^2 - 4x - 2 = 0
x^2 - 2x - 1 = 0
What you get from here is sqrt(2) as one of the roots.
That is not nearly an answer.
4 = 4(x -1)
4 = 4x - 4
8 = 4x
x = 8/4
x = 2
That makes C the answer.
Answer:
Step-by-step explanation:
ΔADC and ΔDBC are similar (AAA)
Therefore the cooresponging sides are in proportion:
Substitute:
<em>cross multiply</em>
Answer:
Some numbers can be divisible by 10 and 5 if they end with 0
Step-by-step explanation:
Answer: x^7+3x^4-9x^2+3
Step-by-step explanation: Simply 1x^7+3x^4-2x^2-(7x^2-3)
x^7+3x^4-2x^2-7x^2+3
-2x -2x
x^7+3x^4-9x^2+3
