What is the ninth term of the arithmetic sequence defined by the rule A(n)= -14+(n-1)(2)

1 answer:

3 0

If you start counting from 0, you ninth term will be 8. Replace n=8 and calculate:
A(8) = -14 + (8-1)(2) = -14 + (7)(2) = -14 + 14 = 0

If you start counting from 1, your ninth term will be 9. Replace n=9 and calculate:
A(9) = -14 + (9-1)(2) = -14 + (8)(2) = -14 + 16 = 2

Answer:

Rectangle and Parallelogram

Step-by-step explanation:

Quadrilaterals are closed figures with four sides. Examples are: square, rectangle, parallelogram etc.

In the given question,

i. one of the parallelograms would be a rectangle since it has 4 right angles and two pairs of parallel lines.

ii. the other would be a parallelogram since it has two pairs of parallel lines and angles are not right angles.

The two quadrilaterals would be rectangle and parallelogram.

Solve the following equation. Then place the correct number in the box provided. 3(2x + 5) ≥ 2(x + 6)

nikitadnepr [17]

(Distribute the 3)
6x +15 ≥ 2(x + 6)
(Distribute the 2)
6x + 15 ≥ 2x +12
(subtract 2x from both sides)
4x + 15 ≥ 12
(subtract 15 from both sides)
4x ≥ -3
(divide by 4x on both sides)
x ≥ -0.75

Hope that helped!
