Answer:
3x^2 - 9x + 8
Step-by-step explanation:
To simplify:
- Distribute the -1 into the second term.
- Collect and combine like-terms (terms with the same variables or powers)
The expression can be rewritten has (2x^2 - 5x + 3) -1(-x^2 + 4x - 5)
After distributing the -1, the equation becomes:
- (2x^2 - 5x + 3) + (x^2 - 4x + 5)
The like-terms are:
- 2x^2 and x^2
- -5x and -4x
- 3 and 5
Combine the like-terms:
- 2x^2 + x^2 = 3x^2
- -5x - 4x = -9x
- 3 + 5 = 8
Substitute the simplified like-terms into the expression, in descending order:
Answer:
Each factory should supply 100 units
x = 100 units
y = 100 units
Step-by-step explanation:
Since the total production must be 200 units, then x + y = 200.
The cost function can be rewritten as a function of 'x' as follows:
The value of 'x' for which the derivate of the cost function is zero, is the production level that minimizes cost:
In order to minimize production costs, each factory should supply 100 units
Area of a square = Length ^2
480 = (x+4)^2
√480 = x + 4
21.9 = x + 4
x = 17.9
Answer:
All real numbers
Step-by-step explanation:
2(x + 1) = 2x + 2
2x + 2 = 2x + 2
2x + 2 - 2x - 2 = 2x + 2 - 2x - 2
0 = 0
All real numbers
The answer is 104 , that’s the answer to your question i think
