Answer:
64
Explanation:
The question is incomplete without the expression that would be used to find the constant necessary to make a perfect square trinomial.
I would show you how to find the constant necessary to make a perfect square trinomial using the expression below:
x² - 16x + c
The expression above is in the form of a quadratic: ax² + bx + c
Where a = 1, b = -16, c = constant
First thing we do, is to square half the coefficient of x
Coefficient x above = b = -16
square of half the coefficient of x = (-16/2)²
Expand it, we have = -16/2 × -16/2 = 8×8 = 64
Replace the constant with 64
x² - 16x + 64
b/2 = -16/2 = -8
(x - 8)² will give a perfect square trinomial
Therefore the constant which makes the above expression a perfect square trinomial is 64
Answer:
- the distribution of earthquakes
- certain fossil distributions
- the distribution of volcanoes
- the location of mountain chains
Explanation:
The plate tectonics are crucial for the processes that happen on the surface or near it on our planet, as well as the physical features of it. The movement of the tectonic plates causes lot of stress when they interact, and from that stress, the crust deep inside cracks and adjusts, which releases a lot of energy and causes earthquakes. Also, on the plate boundaries, because the crust is cracking and is not as tough, the magma from the mantle manages to rise up, and as it reaches the surface it lifts up the land in a cone shape, creating volcanoes, be it as island or continental arcs. When continental tectonic plates collide, they don't subduct, but push against each other, and that enormous pressure lifts up the area around the boundary, gradually giving rise to mountain chains. The fossils are n interesting example as well, as they are one of the best clues about the movement of the tectonic plates. There are lot of fossils that are identical, from the same species, but found on different continents that are not connected in the present, indicating that in the past the continents had different positions and were connected.
