Which polynomial, when added to the polynomial 5x^2–3x–9, is equivalent to x^2–5x+6?

Step-by-step explanation:

We can look at the terms one by one. We know that to get 5 to 1 we must add -4 so the first term is:

For the x term to go from -3 to -5 we must add -2, so the second term is

Lastly, to go from -9 to 6 we must add 15. The final polynomial added is:

tip $2.90

total $17.40

if e is the midpoint of bd, then bd is 14.
