So you basically plug in the x value beside the 5 so if your on number 3 the answer would be 5(3) which is 15
Answer:
A=25 (Rounded)
Step-by-step explanation:
The first step is to find the length of BA which is the base, then you have the find the length of CD, the hight.
To find the distance, you need to use the distance formula which is
(It does not matter if A is x1 or is B is x1, it just has to remain consistent)
I am going to first find BA
Next, subtract accordingly
Once you do that, you want to square -6 and -6 which will give you
Now add 36 with 36 which will leave you with
Do that same thing for CD. If you did it right, you should be left with
to find the area of a triangle, you must use the formula
The Base is (BA) and the Hight is
(CD). substitute to get
Multiply the Base by the Hight to get
Divide 1,296 by 2 to get
Which is equal to
Rounding it to the nearest whole number you get
A=25
Hope this helps. Feel free to ask any follow-up questions.
Have a good day! :)
