Twice a number is increased to 6, the statement in numeric form is written as 2x + 6.
Mathematical actions are called expressions if they have at least two terms that are related by an operator and include either numbers, variables, or both. Adding, subtraction, multiplying, and division are all reflection coefficient operations. A mathematical operation such as reduction, addition, multiplication, or division is used to integrate terms into an expression.
As per the given statement in the question,
Let the number be x.
Twice a number is 2x
And increase by 6 will be,
2x + 6

Answer:
The ball will bounce to 2.07 feet after 4th drop.
Step-by-step explanation:
Bradley dropped a ball from a roof 16 feet high. So, its the initial height.
Each time the ball hits the ground it bounces 3/5 the previous height.
Means after 1st drop, the ball will again rise to feet.
Similarly after 2nd drop, it will bounce to
After 3rd drop, it will bounce to feet
After 4th drop, it will bounce to feet
Hence, the ball will bounce to 2.07 feet after 4th drop.
Answer: 2.0736 ft
Step-by-step explanation:
Bounce 1: 16*3/5=9.6
Bounce 2: 9.6*3/5=5.76
Bounce 3: 5.76*3/5=3.456
Bounce 4: 3.456*3/5=2.0736
