Answer:
<u>x = 4</u>
Explanation:
Add 10 to both sides
-6x = -24
Then divide both sides by -6
-6x/-6 = -24/-6 = 4
x = 4
Answer: Two hydrogen nuclei come together to produce one helium nucleus and two protons, and energy is released.
Explanation:
All stars (including the Sun) at birth begin to fuse two hydrogen nuclei to form helium through nuclear fusion.
In this sense, nuclear fusion is the union of two light atoms, releasing energy in the process, which is the cause of the great luminosity of a star. Especifically, the hydrogen nuclei will begin to fuse, generating helium nuclei in the process and releasing huge amounts of energy.
To unerstand it better:
To shine, the stars transform their hydrogen into helium by means of nuclear fusion. When at half of its life a star is without hydrogen, the nucleus becomes entirely helium and the star declines, becoming colder and brighter due to the energy generated by the nuclear reactions, then the star begins to contract.
Nevertheless, if the star is bigger, this helium will be also consumed and the nucleus transformed in Carbon, then in Oxigen, and so on. Being the last transformation Iron until the star delivers all its energy.
In evolutionary theory, adaptation is the biological mechanism by which organisms adjust to new environments or to changes in their current environment. ... This enables better survival and reproduction compared with other members of the species, leading to evolution.
Answer:
For b. 11*3x = 33x
For c. (3x-4)(11x-2) = 
Explanation:
For b. Since it is a rectangular the A = l*w
w = 11 & l = 3x => A = 11*3x = 33x
For c. Since it is a square we could assume that the A =
a side squared (since they all have the same length) but to be on the safe side, we'll assume it is not a square and do the math of multiplying one side by another (just like for a rectangle)
Side up = 3x + (-4) = 3x-4
Side left = 11x + (-2) = 11x-2
Side up * Side left = (3x-4)(11x-2) =
