You would combine like terms, so it would become 12x +12=180 Then you would subtract 12 from both sides so that the x is on one side and the just plain numbers are on the other side. So your equation now is 12x=168 You then at this point would divide both sides by 12 to get the x alone. Your final answer then would be x=14
Hope this helped Let me know if you have any questions or if you need anymore help. I am always here if you need someone
Answer:
X = 0 or X = -2
Step-by-step explanation:
2x^4 + 16x = 0
x^4 + 8x = 0
x(x+2) (4+x^2_2x) = 0
x + 2 = 0
or
4+x^2_2x=0
The plane of cross section and the basis plane are parallel, so each lateral face of the prism is intersected by parallel planes and their intersection lines are parallel.
Since the cross section is a polygon with eight sides (each side of this polygon is parallel to coresponding side of basis), then basis is also a polygon with eight sides.
Answer:
Step-by-step explanation:
Ratios of perimeters is a one-to-one measure. From the figure on the left to the one on the right the ratio of the one-to-one measure is 45/25 which reduces to 9/5.
Area is a squared measure. Once we have the perimeter reduced (we do), we square those perimeter measures to find the area ratio.
