The answer is B.
This is because the triangle is an isosceles triangle, meaning that the answer to 4x-8 = x+4
You can rearrange this question to put the x’s on both sides and the integers on both sides so that 4x-x = 4 + 8. This cancels down to 3x = 12. To find x, divide 12 by 3, which is 4.
To check this answer, you can input 4 into both of the equations. (4 x 4) - 8 = 8, and 4 + 4 is also 8. Hence, you know x = 4.
Another, more time-consuming way of doing this question would be to simply input each possible value (A, B, C and D) into both equations until the both equations came out with the same number.
Hope this helped :)
Answer:
The closer the rocks are to the mid-ocean ridge the younger they are, and the further away they are the older they are.
Explanation:
The ocean floor gives us one of the best if not the best evidence for the movement of tectonic plates, and definitely the best when it comes to ocean floor spreading. When the convection currents are stronger at parts, they manage to break up tectonic plates, moving them apart, and gradually forming an ocean.
The magma that is pushed through the gap is quickly cooling off and solidifies into a new rock on the ocean floor. Because magma keeps coming constantly for millions of years, the new rock that forms constantly pushes away the preexisting rock. This leads to a situation where the youngest rocks are always found at the mid-ocean ridge because it is there where they form. The further a rock is from the mid-ocean ridge the older it is. The oldest rocks are found at the edges of plate boundaries that are on the opposite sides of the mid-ocean ridge, and they often tend to be a subject of subduction.
