Subtract: (x2 − 8x + 5) − (−3x2 + 5x − 9) me .

The answer is option D, 4x2 − 13x + 14.

Step-by-step explanation:

Step 1: Distribute any coefficients.

In this case, there aren't any, so a 1 will be presumed in front of each set of parentheses. A positive 1 in front of the first, and a −1 in front of the second, as a result of the subtraction symbol.

The first set will remain unchanged, but the "(−3x2 + 5x − 9)" will be affected. This will give you:

x2 − 8x + 5 − 3x2 − 5x + 9

Step 2: Identify and combine like terms.

x2 and 3x2 will go together = 4x2

−8x and −5x will go together = −13x

And lastly, 5 and 9 will be added = 14

Therefore, your answer will be 4x2 − 13x + 14.

I hope this helps!

not only in mathematics, scientific proof also are required in the other field of science. also maths proofs are of particular structure, containing steps and logics. so proving is like doing science, it is science. that's why it is important to prove. 

an inaccurate proof leads to errors, or stating results that are not accurate.  which wil mess the probelm up you dont want this

answer: the distance

step-by-step explanation:

to calculate the distance d of a line segment with endpoints (x1, y1) and (x2, y2) use the formula d (x2 x1)2 (y2 y1)2. to calculate the midpoint of a line segment with endpoints (x1, y1) and (x2, y2) use the formula
