The overall specific gravity of the earth is much higher than the specific gravity of crustal rocks which means the earth is about twice as heavy as the rocks on the surface would suggest. Iron meteorites are thought to have the same composition as the average earth, and the meteorites contain a lot more iron than the Earth's surface rocks.
True I think but don’t take my word on it
Answer:
11
Explanation:
XP = XZ - PZ = 7x + 1 - 4x + 1 = 3x + 2
Since XP = PZ (according to the properties of a parallelogram)
--> 3x + 2 = 4x - 1
--> x = 3
Now we simply put x = 3 back to the 3x+2 in the beginning which means XP = 3 x 3 + 2 = 11
And no I do not need a date but good luck finding one!
