Answer:
P = 6x³ + 12x² - 18x + 8
Step-by-step explanation:
Given that:
Length = 3x3+4x2−6x
Width = 2x2−3x+4
The length of fencing needed will be :
Perimeter of rectangle (P) = 2( Length + Width)
P = 2[ (3x3+4x2−6x) + (2x2−3x+4)]
P = 2 (3x³+ (4x² + 2x²) + (-6x - 3x) + 4)
P = 2(3x³ + 6x² - 9x + 4)
P = 6x³ + 12x² - 18x + 8
Answer:
x=180°
Step-by-step explanation:
![cos x+1=0\\cos x=-1=-cos0=cos(\pi -0)=cos \pi \\x=\pi =180^\circ](https://tex.z-dn.net/?f=cos%20x%2B1%3D0%5C%5Ccos%20x%3D-1%3D-cos0%3Dcos%28%5Cpi%20-0%29%3Dcos%20%5Cpi%20%5C%5Cx%3D%5Cpi%20%3D180%5E%5Ccirc)
