We need to look at the number after the tenth, called the 'hundredth'. If the hundredth is 5 or above, we must change the hundredth to 0 and make the tenth one higher.
In this case, the hundredth is 9 and is above 5, so it becomes 0 and the tenth moves higher to become 9.
The number will now be 1.9
Subtract each polynomial. Note that you combine like terms
(2 - 4x^9 + 3x^3) - (7x + x^3 - 6 + 12x^4)
Distribute the negative to all terms within the second parenthesis
(2 - 4x^9 + 3x^3) + (-7x - x^3 + 6 - 12x^4)
Combine like terms
4x^9 - 12x^4 + 2x^3 - 7x + 8 is your answer
hope this helps
So based on your question about the line A and B meet and the four lines are congruent to each other. The graph doesnt show any measurements so there is no exact value to the length of X. But you must consider that the lines are proportional to each other so it means that they are congruent.
