It has to be true because
X + 9 = 2 ( x - 1 )²
x + 9 = 2 ( x² - 2 x + 1 )
x + 9 = 2 x² - 4 x + 2
- 2 x² + 4 x + x - 2 + 9 = 0
- 2 x² + 5 x + 7 = 0 / * ( -1 )
Answer:
A ) 2 x² - 5 x - 7

Answer:
X=1
Step-by-step explanation:
1. You subtract 6x with 9x so it should equal 2=3x-1
2.You add 1 to the 2 so it should be 3=3x
3.You divide 3 on both sides so it should be 3/3=3x/3
4.After you divide you finally get the answer 1=x or x=1
Sine is define as the opposite divided by the hypotenuse
sin M = 12/37
12 is the opposite, and 37 is the hypotenuse
