A blue whale weight = 200 short tons (400,000 pounds)
A african elephant weight = 3 tons (9,000 pounds)
And then you would minus the tons and get your answer
hope this helped :)

![3 \div \frac{1}{2}](https://tex.z-dn.net/?f=3%20%5Cdiv%20%20%5Cfrac%7B1%7D%7B2%7D%20)
=
![3 \times \frac{2}{1}](https://tex.z-dn.net/?f=3%20%5Ctimes%20%20%5Cfrac%7B2%7D%7B1%7D%20)
= 6

![5 \div \frac{5}{3}](https://tex.z-dn.net/?f=5%20%5Cdiv%20%20%5Cfrac%7B5%7D%7B3%7D%20)
=
![5 \times \frac{3}{5}](https://tex.z-dn.net/?f=5%20%5Ctimes%20%20%5Cfrac%7B3%7D%7B5%7D%20)
= 3
20 is 1/5 of 100 so do 20x5=100 and 15x5=75
So there is a 75% chance she will make the goal
Answer: (x + 7)(x - 7)
Explanation: If a variable is taken to an even power, that variable is a perfect square. In this case, x² would therefore be a perfect square.
Since 49 is also a perfect square, what we have here is the difference of two squares. That can be factored as the product of two binomials one with a plus in the middle and one with a minus in the middle.
In the first position will be the factors of x² that are the same.
So we have <em>x</em> and <em>x</em>.
In the second position we will have the
factors of 49 that are the same, 7 and 7.
(x + 7)(x - 7) is your answer which is a factored version of x² - 49.
