Answer:
-3/2 x -1/2
Step-by-step explanation:
hello :
-1/2(-3x+6x+1)-3x =3/2 x-3x -1/2 = (3/2 - 3)x -1/2 =-3/2 x -1/2
Yes, but the answer I think the question is asking for is 5/4, not 1 1/4 since a fraction greater than one is usually that the numerator is greater than the denominator or known as a improper fraction. I'm not sure if my answer is correct but I think it is.
The simplified form of this polynomial is (n(20n + 1))/5
Given the question, it needs the points so that the equation can be evaluated and to know if the points is a solution to the equation or not.
Look at the picture.
![\cos 75^\circ =\frac{x}{25} \\ 25 \cos 75^\circ = x \\ 25 \times 0.2588 \approx x \\ x \approx 6.47](https://tex.z-dn.net/?f=%5Ccos%2075%5E%5Ccirc%20%3D%5Cfrac%7Bx%7D%7B25%7D%20%5C%5C%0A25%20%5Ccos%2075%5E%5Ccirc%20%3D%20x%20%5C%5C%0A25%20%5Ctimes%200.2588%20%5Capprox%20x%20%5C%5C%0Ax%20%5Capprox%206.47)
