Answer:
its 3
Step-by-step explanation:
i know that bc u keep mince
(3x-5)(2x-7)
6x^2 - 21 x -10x +35
6x^2 -31x +35
The first one
Easy
first term is n=1
so 10th term is n=10
5(10)+100=50+100=150
150 is 10th term
Answer:
16:12
Step-by-step explanation:
(4+12)=16
16/4 = 4
4x3=12
Another method:
4---------3
16-------x
Cross multiplication
4x=16x3
4x=48
x=12
Answer:
Below
Step-by-step explanation:
sin(2x) = 2 ×cos(x)× sin(x)
● sin(x) = 2 × cos(x) × sin(x)
● 2 × cos(x) = 1
● cos (x) = 1/2
So we can deduce that:
● x = Pi/3 + 2*k*Pi
● or x = -Pi/3 + 2*k*Pi
K is an integer
