(n+2)^4 =
(n²+4n+4)(n²+4n+4) =
n^4 + 4n³ + 4n² + 4n³ + 16n² + 16n + 4n² + 16n + 16 =
n^4 + 4n³+24n²+ 4n + 16
Hope this helps
The calculation for circumference is 2πr or 2 × π (pi=3.14) × radius of a circle
Since the diameter of this circle is 7cm, and the radius is half of the diameter, 7 ÷ 2 = 3.5
So, 2×3.14(π)×3.5=21.98
Answer:
17.82
Step-by-step explanation:
since this is a right triangle you can use one of the trigonometric ratios, in this case it would be cosine because you have values for the adjacent and hypotenuse sides
cos(27°) = x/20
x = 20 · cos(27°)
x = 17.82
