Anything 5 and up, because when you multiply the by 15, they equal more than 65, making the inequality true.
Sum of n terms = a1 (r^n-1/ (r-1)
Sum of first one = 3 * (4^5 - 1) / 3 = 1023
.. 2nd = 5 * (6^2 - 1) / 5 = 35
.. 3rd = 5 ^4 - 1 / 4 = 156
.. 4th = 4 * (5^4 - 1) / 4 = 624
So in increasing order its 2nd, 3rd, 4th and first.
Answer:
x = -2,3
Step-by-step explanation:
Given: (x − 3)(x +2) = 0
To find the solution of above factor.
It is already in factor form.
Two factors are (x-3) and (x+2)
So, set each factor to 0 and solve for x
(x − 3) = 0 or (x +2) = 0
x - 3 = 0 or x + 2 = 0
x = 3 or x = -2
Hence, The solution of the (x − 3)(x +2) = 0 are 3 and -2
