Answer:
Below in bold.
Step-by-step explanation:
The hexagon is made up of 6 equilateral triangles.
So the Base = 12 cm.
Height a = 12 cos 30 = 10.392 cm
So area of 1 triangle = 1/2 * 12 * 10.392 cm^2
- and total area = 6 * 1/2 * 12 * 10.392
= 36 * 10.392
= 374.11 cm^2 to the nearest hundredth.

Answer:
k = 4.
Step-by-step explanation:
An arithmetic sequence has a common difference.
So for this to be arithmetic:
k + 3 - (k - 1) = 3k - 1 - (k + 3)
k + 3 - k + 1 = 3k - 1 - k - 3
3 + 1 = 2k - 4
4 + 4 = 2k
k = 4.
The sequence is 3, 7, 11.
The correct answer is: -2x > 6!
-2x > 6
-2x / -2 > 6 / -2
x > -3
Hi,
(4x−2)(3x^2−2x+1)
=(4x+−2)(3x^2+−2x+1)
=(4x)(3x2)+(4x)(−2x)+(4x)(1)+(−2)(3x2)+(−2)(−2x)+(−2)(1)
=12x3−8x^2+4x−6x^2+4x−2
=12x3−14x2+8x−2
Have a great day!
