1 answer:
You will have to figure out the last equation but here is the rest:
You might be interested in
a1 = 1 and d = 4
a(n) = a1 + d(n - 1)
a(n) = 1 + 4(n - 1)
-9T means -9 x T
So if T is equivalent to 4,
you should do:
-9 x 4 = -36
J= -36
X^2 + 3x - 4 = 6
x^2 + 3x -10 = 0
(x + 5)(x - 2) =0
x = -5 or x = 2
solution set is {-5,2}
