The answer is 7 because honestly I just don’t know what to put
Answer:
1. x ≤ -8
2. y < -8
3. y < -11
4. n > 10
5. n ≤ -2
6. n ≤ 15
7. n ≤ -5
Step-by-step explanation:
Your goal is to get just the variable on one side of the inequality!
For example, take -2y - 4 > 18.
Add 4 to both sides. So... -2y - 4 + (4) > 18 + (4)
Now you get -2y > 22. Since y isn't by itself, let's divide both sides by -2.
So, (-2y / -2) > (22 / -2)
<u>Anytime you're dividing something by a negative, remember to FLIP THE SIGNS.</u> So instead of a greater than, it will now be a less than sign <.
Now you get, y < -11
The shaded region's area is x² + 23x + 49.
Step-by-step explanation:
Step 1; To calculate the area of the shaded region, we subtract the area of the square which has side lengths of (x + 1) from the entire rectangle. So we determine the equations that denote the areas of the two shapes.
Step 2; Area of the square = side length × side length (x + 1)×(x + 1) = x² + x + x + 1 = x² + 2x + 1
Area of the bigger rectangle = length × breadth = (x + 10) × (2x + 5) = 2x² + 5x + 20x + 50 = 2x² + 25x + 50.
Step 3; The given shaded region's area = Area of the bigger rectangle - Area of the smaller square = 2x² - x² + 25x - 2x + 50 - 1 = x² + 23x + 49.
So the shaded region's area of x² + 23x + 49.
