Answer:
b+7
Step-by-step explanation:
To simplify an equation, you combine like terms and remove redundancies. Like terms are 4b and 3b, another pair of like terms are 9 and 2. Let's combine them. 4-3 is 1, so we can make the equation into 1b+9-2. We can simplify that to b+9-2. But wait, we can combine 9 and 2. 9-2 is 7, so the final simplified equation is b+7. I hope this helps!
Answer:
452.39
Step-by-step explanation:
The question is asking for the area of the pool, so use the circle area formula, which is A=
. In the formula, A is the area and r is the radius. The question gives us the diameter, so divide that by 2 to get the radius. Therefore the equation is A=
, then solve to get 452.39.
