- ∆ABD is right angled hence area:-




There is only one option containing 6x^2 i.e Option D.
Hence without calculating further
Option D is correct
The correct answer is C) (5m^50 - 11n^8) (5m^50 + 11n^8)
We can tell this because of the rule regarding factoring the difference of two perfect squares. When we have two squares being multiplied, we can use the following rule.
a^2 - b^2 = (a - b)(a + b)
In this case, or first term is 25m^100. So we can solve that by setting it equal to a^2.
a^2 = 25m^100 -----> take the square root of both sides
a = 5m^50
Then we can do the same for the b term.
b^2 = 121n^16 ----->take the square root of both sides
b = 11n^8
Now we can use both in the equation already given
(a - b)(a + b)
(5m^50 - 11n^16)(5m^50 + 11n^16)

Answer:
$51.1
Step-by-step explanation:
If Joe spent 15/22 of his pocket money in a story book which costs $75, he had $51.1 at first.
15/22 of 75 = 51.1363636364 or 51.1
