answer: an equation is a set of numbers put together within a problem that you are meant to solve in order to receive the final answer.
Answer:
The answer to your question is: letter C
Step-by-step explanation:
4x² + 5x - 6
Process
4 x - 6 = - 24
Find two numbers that added gives + 5 and multiply gives -24
These numbers are + 8 and - 3
4x² + 8x - 3x - 6
4x ( x + 2) - 3(x + 2)
(x + 2) (4x - 3)
Answer:
Alexander is incorrect because the expressions are not equivalent.
Step-by-step explanation:
If the expression is evaluated for any value of x, y; the result will not be same.
For instance, let assume x = 1 and y = 2
3x + 4y = 3 + 4 = 7
(3)(4) + xy = (3)(4) + (1 * 2) = 12 + 2 = 14
So, the expressions are not the same and Alexander is incorrect.
