Answer: Rico is right.
(-1)(3x + 5)²
Step-by-step explanation: If it were the difference of two squares, the -30x would not be there.
It makes sense to factor out (-1) fry the trinomial, leaving all positive terms.
Then factor 9x² + 30x + 25 as
(3x + 5)²
Answer:
Step-by-step explanation:
The volume of a cone is given by the following equation:
where is the volume of the cone, is the radius of the base, and is the height of the cone.
In the given problem, we know that and . Using this, we can find the volume of a single cone:
Since the problem asks how much foam is needed to make 120 cones, we can multiply this result to get our answer:

Hello! I hope I am correct! :)
Step-by-step explanation:
Let’s first calculate the black circle & the white space.
Since there is more white space than the black circle, we already know that the white space will have more probability.
These are the steps you need to do, in order to so love this problem:
1. Find the area of both, the white space and the black circle.
2. Divide both of them by the area of the square.
3. Do all these steps to find the probability/hitting.
Part A:
Black circle: ( π *1^2) / ( π 5^2) = 1/25 = .04 or 3.14% chance.
So we can tell it’s close to zero.
Part B: 1 - .04 = 0.96 or 97%
This is close to one.
(Remember I am not saying the exact, it’s a estimate)
