<u>Answer:</u>
The area of the shape is 68 cm².
<u>Step-by-step explanation:</u>
We have to calculate the areas of the rectangle and triangle separately, and then add them together.
• Area of rectangle = length × breadth
= 30 cm × 2 cm
= 60 cm²
• Area of triangle = × base × perpendicular height
= × 2 cm × 8 cm
= 8 cm²
Adding the areas together = 60 cm² + 8 cm²
= 68 cm²

Answer:
-4 ≤ f () ≤ 4
Step-by-step explanation:
The range of a function is the allowed y-values of the function.
We can simply look at the periodic function below and see that the y-value ranges from a negative 4 to a positive 4. It oscillates betwen -4 and 4. That is the range.
We can say -4 ≤ f () ≤ 4

Answer (depending if the fraction is positive or negative):
- x ≥ 18
- x ≤ -18
Step-by-step explanation:
If the fraction is positive:
- Write it out:
- Multiply each side by 6 to cancel out the 6 under x. It should now look like this: x ≥ 18
If the fraction is negative:
- Write it out:
- Multiply each side by -6 to cancel out the -6 under x. It should now look like this: x ≤ -18
