Answer:
g=3
Step-by-step explanation:
multiply x with x-4 and +7 with x-4 to open the brackets
x^2 - 4x + 7x - 28 = x^2 +gx - 28
x^2 + 3x - 28 = x^2 + gx -28
x^2 - x^2 + 3x -28 + 28 = gx
gx is kept alone on the other side because we have to find value of g
cancel out +x^2 -x^2 and +28 -28
we ll be left with
3x = gx
divide both sides by x
3x/x = gx/x
cancel out x in the numerators with the x in the denominators
3 = g
The answer is 3. You have to count up from -6. -5,-4,-3,-2,-1,0,1,2,3
Answer: 48
Step-by-step explanation:
The 17th term is 50C16*2^34*a^16
The 18th term is 50C17*2^33*a^17
The ratio of these two terms is (17th term)/(18th term) = 1/a. We want the value of this to be 1, so
.. A = 1
_____
My calculator says
.. 50C16 = 4,923,689,695,575
.. 50C17 = 9,847,379,391,150
the latter being exactly 2 times the former.
