7n^2 + 5 = 453
Subtract 5 from both sides:
7n^2 = 448
Divide both sides by 7:
N^2 = 64
Take the square root of both sides:
N = 8
Answer: x = 55/2
Step-by-step explanation: (x)(2) (-3)(2) = 49 2x-6+6 = 49+6 2x/2 = 55/2 x = 55/2
I know that my answer isn't a choice for one of the values of x but that's the result that I got when I solved (x–3)2 = 49.
Answer:
the answer is 11%
Step-by-step explanation:
this is because
27/30x100=90
which is 90
but the difference between 100 and 90 is 10
so its 10% but its closer to 11%
so yeah
i am not sure if its correct
Cos²(x) + sin²(x)
¹/₂[1 - cos(2x)] + ¹/₂[1 + cos(2x)]
[¹/₂ - ¹/₂cos(2x)] + [¹/₂ + ¹/₂cos(2x)]
¹/₂ + ¹/₂ - ¹/₂cos(2x) + ¹/₂cos(2x)
1
