The product of two consecutive positive integers is greater than their sum by 209.
Akimi4 [234]

Answer: 15 and 16

Explanation:

You can set up an equation N is one positive integer, and N+1 is the second (because they are consecutive, so it's the first number plus one).

Equation to solve for N

N(N+1) = N + (N+1) + 209

N^2 + N = 2N +1 + 209

N^2 - N - 210 =  0 (factor here)

N = 15 or N = -14

Since the question asks for the positive integers, you know the first number is 15, then the next would be 16.

Certain noteheads can only be placed on staff lines.
professor190 [17]

The statement Certain noteheads can only be placed on staff lines is: "False.

<h3>What is noteheads?</h3>

Noteheads can be placed on staff lines or in the spaces between them. The position of the notehead determines the pitch of the note. A notehead on a line or space corresponds to a specific letter name (A, B, C, D, E, F, or G) and octave (the range of pitches from one C to the next C).

For example, in the treble clef, the notehead on the bottom line of the staff is an E, and the notehead in the space above it is an F. The notehead on the top line of the staff is an F, and the notehead in the space above it is a G.

Sometimes, noteheads need to be placed above or below the staff to indicate higher or lower pitches. In this case, ledger lines are used to extend the staff. A ledger line is a short horizontal line that acts as a staff line for a single note. A notehead can be placed on a ledger line or in the space between ledger lines.

For example, in the treble clef, the notehead on the first ledger line above the staff is an A, and the notehead in the space above it is a B. The notehead on the second ledger line above the staff is a C, and the notehead in the space above it is a D.

Here is an example of noteheads on staff lines, in spaces, and on ledger lines in the treble clef:

D

B |   |

 E F G A B C D

"

Therefore the statement is false.
