Using formula sin^2 x +cos^2 x = 1 you get 1 - cos^2(9x) = sin^2(9x)
so in this way this fraction will be rewrited
sin9x/(1-cos^2(9x) = sin9x / sin^2(9x) = 1/sin9x
Answer: x = 4
<u>Step-by-step explanation:</u>
6ˣ = 1296
6ˣ = 6⁴
Since they have the same base, set the exponents equal to each other:
x = 4
1. First, you multiply 147 x 10 which equals 1470. 2. Then, you add 1470 plus 3, which is 1473/10.
2(x - 4) + 7(x + 2)
mutiply the first bracket by 2
(2)(x)=2x
(2)(-4)= -8
mutiply the second bracket by 7
(7)(x)=7x
(7)(2)= 14x
2x-8+7x+14
2x+7x-8+14 ( combine like terms)
Answer:
9x+6 or 6+9x
Answer:
x+6=9
Step-by-step explanation:
divide all by 5
