Answer:
XIX
Step-by-step explanation:
X is 10 and IX is 9 as I is 1 so it is I (1) - X (10)
A is perpendicular to c<span />
The values of a, b and c can be easily determined if we arrange the terms of the given quadratic expression from the highest power to the lowest such as 8X²-2X-1=0.
Tha value of variables a, b, and c are enumerated below:
a=8
b-2
c-1
What's the question? I am guessing the answer would be if he is correct or not.
Without the picture, it would a harder to tell.
Let's start by giving an example. Let's say 2 plots of land both have an area of 12 units. 1 of the plots could be 2 units length and 6 units width. The other could be 3 units length and 4 units wide.
The second example- Both areas are 25 first plot could be 2 units length and 25 unit width. The other plot could have 5 units length and 10 units width.
Hope you can find the answer in these examples. Even though their shapes and dimensions are different, they can still have the same area.
