When you subtract flip the signs of the second set.
2x^2+5-4x+3
Now combine like terms

Final answer: B
How are you supposed to solve this???
(red pens + black pens) / total pens
(4 + 6) / 15 = 10/15 = 2/3
Answer:
X = 1 2 3 4 5 6
P(x) 1/2 1/6 1/12 1/12 1/12 1/12
Step-by-step explanation:
I found those two possibilities, hopefully they're correct:
8² + 1² = 8 * 8 + 1 * 1 = 64 + 1 = 65
7² + 4² = 7 * 7 + 4 * 4 = 49 + 16 = 65
I hope it will help you :)
