3x + xy^2 + 5x - 2xy ok so once you can decode the sentence this is what it will look like. First you add the common facts which are 3x and 5x which = 8x ok so now we have 8x + xy^2 - 2xy so then I believe you cant do anything after that because there will be no more common factors hey can you tell me if I am write if you have already had turn this in please hope this helps

Answer:
10%
Step-by-step explanation:
In this question, we are asked to calculate the percentage error in a measurement.
This can be obtained by first getting the error involved. That is calculated by Subtracting the value calculated from the actual value. That is 9.5 - 8.9 = 0.6
The percentage error is thus 0.6/9.5 * 100 = 6%
The value is actually 10% to the nearest tenth of a percent
A. a + ( - a)
Because it’s the same thing as: a - a
And if you plug in any value for example:
2 - 2 that would be 0
