Answer:
B is Geometric and its next terms are 81, 243, 729...
See example below to complete other problems.
Step-by-step explanation:
Geometric sequences have a pattern that is exponential. Because of this, they do not have a constant rate of change using addition or subtraction. Instead, they have a constant rate through multiplication and division called a common ratio. Problem B is geometric because as you subtract each y value you get a different value each time. It is not a common difference. But if you divide, you find a common ratio.
Example: 27-9= 18 27/9 = 3
9-3 = 6 9/3 = 3
etc. Common ratio of 3
Answer:
13n - 39 = 39
Step-by-step explanation:
Let the number be n. Then we have 13n - 39 = 39
Im pretty sure it would be 10??? if you are putting it as a subtraction problem if not i would try wording it more clearly
Carlos factored incorrectly because he didn't simplify the trinomial like Sophie did. They both will have the same answer, but Carlos needs to simplify before factoring.
The area of the parallelogram using area of rectangle and area of two triangles is 84 m²
<h3>How to find area of a parallelogram</h3>
- Area of a rectangle = length × width
= 8m × 7m
= 56 m²
- Area of each triangle = 1/2 × base × height
= 1/2 × 4m × 7m
= 1/2 × 28
= 14m²
- Total area of triangles = 2(14 m²)
= 28 m²
- Area of parallelogram = area of rectangle + area of two triangles
= 56 m² + 28 m²
= 84 m²
