75,000 divided by 150, is 500, meaning they allow 500 people per acre. 500 times 145 is 72,500, meaning the capacity for a park your size should be 72,500 people.
X equals 4 and the x axis
Answer:
No
Step-by-step explanation:
Let's check the first statement with an example. 2 and 3 are positive numbers and their sum (5) is also positive so his first statement is true.
To check the second statement let's look at the negative numbers -1 and -8 for example. Their sum (-9) is also negative so his second statement is true.
To check the third statement let's look at the numbers 9 and -5. One is positive and one is negative, but their sum (4) is positive, so his third statement is false. However if we look at the numbers 4 and -7, their sum is negative so the third statement is partially false.
<span>Question :
The length of a side of a square is . If the area of the square is 12, find x.
Answer :
</span>
![area\ of\ the\ square = side \times side](https://tex.z-dn.net/?f=area%5C%20of%5C%20the%5C%20square%20%3D%20side%20%5Ctimes%20side)
