Galileo had substantial proof that he collected from his discovery of the telescope. Thus, people believed it more easily.
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:
Rust.
Explanation:
First, the acidified water will dissolve some of the iron by removing electrons. Then, the water will begin to break down into hydrogen and oxygen. Free oxygen reacts with dissolved iron to form iron oxide, and iron oxide is rust.
