ily the only way to solve. For example, the equation 2(x + 3) = 16 could be solved by dividing the equation through by 2 to get x + 3 = 8.

This is because simplifying the equation before solving it will lead you to the answer at a much faster rate. For example, in the given equation, the long way would be to distribute 2 to (x+3). Then, you transpose them and combine like terms. Until you get to x + 3 = 8. But if you simplify it first, you will see that it is straightforward. It will lead you to the answer right away which is x + 3 = 8. It saves you from the hassle of doing more algebra :)

irga5000 [103]

Answer: 27 players will be notified during the third round of calls.

Step-by-step explanation:

In case the game is canceled, the coach calls three players. This means that if each of these three players call three more players, the number of players that will be notified during second round of call would be

3 × 3 = 9 players.

If each of these nine players call three more players, the number of players that will be notified during third round of call would be

9 × 3 = 27 players.

The total number of players that would have been notified is

3 + 9 + 27 = 39 players

The ___________ formula measures the length of a line segment or the distance between two points.
Morgarella [4.7K]
The distance formula measures the length of a line segment or the distance between two points.

The hypotenuse is one of the two sides that forms the right angle of a triangle.

The altitude of a triangle is a line segment that extends from the vertex and is perpendicular to the side opposite the vertex.

Anvisha [2.4K]

Answer:

x = 27

Step-by-step explanation:

∠ CAD and ∠ EDF are corresponding angles and are congruent, so

∠ CAD = 2x

The sum of the 3 angles in Δ ABD = 180°

sum the angles and equate to 180

72 + 2x + 2x = 180

72 + 4x = 180 ( subtract 72 from both sides )

4x = 108 ( divide both sides by 4 )

x = 27
