Answer:
Why are you giving us the answer..?
The sum of the two numbers is equal to 70.
- Let the first number be x.
- Let the second number be y.
In this exercise, you're required to find two numbers by translating the word problem into an algebraic expression and then solving for the unknown variables (x and y).
Translating the word problem into an algebraic expression, we have;
Two numbers differ by 8:
....equation 1.
The product of the two numbers is 713:
....equation 2.
To calculate the sum of the two numbers:
First of all, we would solve for each of the unknown variables (x and y).
From eqn. 1, we have:
....equation 3.
Substituting eqn. 3 into eqn. 2, we have:
Solving the quadratic equation by factorization, we have:
y = -23 or 31.
For the value of x, when y = 31:
x = 39
Now, we can calculate the sum of the two numbers:

No you should not just walk out of class.
Bromine has stronger inter molecular force than Fluorine.
<h3> Inter molecular forces and relationship with physical states of matter</h3>
The intermolecular forces of a substance tells the physical state of that substance , We can therefore say that the Solid, liquid and gas states of substances depends on the intermolecular forces surrounding them.
- For solids,the inte molecular forces will be so strong as they draw the molecules together giving them a compact structure.
- For liquids, the the inter molecular forces will be just strong enough to keep the molecules together in a confined space.
- For gases, the the inter molecular forces are weakest as the molecules move about.
We can then conclude that At stp, fluorine is a gas and bromine is a liquid because, compared to fluorine, bromine has a stronger intermoleclar force.
