Answer is x² + 2x + 5
<u>Step-by-step explanation:</u>
Step 1:
Add the two polynomials
⇒ (2x + 7) + (x² - 2) = 2x + 7 + x² - 2 = x² + 2x + 5
False...it does not include 3....it includes only numbers less then 3.
For it to include 3, u would need an equal sign in there..
Y < = 3...(thats less then or equal)...this would include 3
160/4 = 40 mph so that would be the answer simply divide
The probability would be 15 over 24.
We can tell this because by the table, the number 2 was rolled 4 total times, the number 4 was rolled 9 total times and the number 6 was rolled 2 total times. When you add those together you get 15. You can state the probability by expressing with the number of times rolled over total times rolled. Since it was rolled a total of 24 times, we are left with 15/24.
