Answer:
No it would be a Arithmetic sequence because it’s adding, not multiplying.
Step-by-step explanation:
Arithmetic sequences use addition, so each term is a constant amount (common difference) more or less than the last.
Geometric sequences use multiplication, so each term is multiplied by a constant amount (common ratio) to get the next one.

Answer: (1) Sometimes, only if the parallelogram is also a rhombus. 13. A rectangle is a square. ... A square has opposite angles congruent. o Always, all parallelograms have opposite sides congruent. 16.
(2) Some rectangles may be squares, but not all rectangles have four congruent sides. All squares are rectangles however. The correct answer is that all trapezoids are quadrilaterals.
(3) Every square is a rhombus, and a rhombus can be a square, if all its angles are 90 degrees. Thus, a rhombus can be a rectangle (if the angles of the rhombus are all 90 degrees), and a rectangle can be a rhombus (if the sides of the rectangle are all equal length).

Answer:
There are 35 blue marbles
Step-by-step explanation:
b = blue marbles
r = red marbles
r+b = 48
b = 2r+9
Substitute b =2r+9 into the first equation
r + (2r+9) = 48
Combine like terms
3r +9 = 48
Subtract 9 from each side
3r+9-9 = 48-9
3r = 39
Divide each side by 3
3r/3 = 39/3
r = 13
There are 13 red marbles
We need to find the blue marbles
b =2r+9
b = 2(13) +9
= 26+9
= 35
There are 35 blue marbles
