Answer:
y = x² + 11x + 24
Step-by-step explanation:
y = (x + 3)(x + 8)
Expand
y = x² + 8x + 3x + 24
Combine like terms
y = x² + 11x + 24
Answer: 9
Step-by-step explanation:
If 12 is the whole length, and 3 is a small section of it, then 3 + j = 12
Or 12 - 3 = j
Therefore, 12 - 3 = 9

Step-by-step explanation:
Answer: 0
Explanation:
1) Cosine trigonometric ratio definition:
cos (α) = adjacent-leg / hypotenuse
2) P (0,1) ⇒
- adyacent-leg = x-coordinate = 0
- opposite-leg = y-coordinate = 1
- hypotenuse = √[x² + y² ] = 1
3) Therefore, cos(α) = 0 / 1 = 0
Answer:
2 hours
Step-by-step explanation:
If Thomas can paint 1/3 = 2/6 of the room in a hour and Brian can paint 1/6 of the room in an hour. Which means in an hour they can collectively paint 3/6 = 1/2 of the room. Now you need to find how long it would take then to paint 2/2 of the room. Knowing that 1/2+1/2 = 2/2, it would take them 2 hours to paint the room together
