Answer:
Answer:
The manager's prediction is false
Step-by-step explanation:
Given
Jacob: 2000x + 4000
Carlos: 3500x - 40000
Required
Determine if both expression will be the same if x = 35
To do this;
Equate both expressions and then solve for x
i.e.
2000x+4000=3500x-40000
Collect Like Terms
2000x+4000=3500x-40000
-1500x=-44000
Divide both sides by -1500
Hence, the manager's prediction is not true because x
35
Remember that the sum of tow cubes identity is:
So, to create our expression<span>, containing at least two variables, that can be factored using the sum of two cubes, we just need to replace </span>
and
with tow monomials with a different variable:
and
Lets replace those values in our identity:
Now that we have our expression, lets factor it using the sum of two cubes identity:
To verify if the factored form of our expression (right hand side) is equivalent to the original form (left hand side), we are going to expand the right hand side:
Since both sides of the equation are equal, we can conduce that the factored form of our expression is equivalent to the original expression.
