Answer:
To find the area of the polygon with the given vertices A(-5, 0), B(0, 10), and C(15, 0), you can use the formula for the area of a triangle when you have the coordinates of its vertices. The formula is:
Area = 1/2 * |x1(y2 - y3) + x2(y3 - y1) + x3(y1 - y2)|
In this case, A(-5, 0), B(0, 10), and C(15, 0), so you can plug in these coordinates into the formula:
Area = 1/2 * |-5(10 - 0) + 0(0 - 0) + 15(0 - 10)|
Simplify the expression inside the absolute value:
Area = 1/2 * |-50 + 0 - 150|
Now, continue simplifying:
Area = 1/2 * |-200|
Since we're taking the absolute value, it becomes:
Area = 1/2 * 200
Now, calculate the area:
Area = 100 square units
So, the area of the polygon is 100 square units.
You can also use the distance formula, but this way is faster to me :-p
The Value of x=±
To find the value of X.
Any equation containing one term in which the unknown is squared and no term in which it is raised to a higher power.
Assuming
a≠0...
First subtract c from both sides to get:
Divide both sides by a and transpose to get:
So x must be a square root of and we can deduce:
x=±
So, the Value of x=±

Step-by-step explanation:
Mandela served as president of South Africa for five years.
Challenges can be overcome through hard work and persistence.
Mandela encouraged peace in his country while he was president.
Answer:
In Nelson Mandela's family he was the first to receive a formal education. At that time, very few black kids attained high school education in South Africa.
if the length is 8ft and the width is (7+x) then the area would be 56+8x, if x is unknown.
Answer: The distance between these points is 5 units.
Step-by-step explanation:
We know that by Distance formula , the distance between two points (a,b) and (c,d) is given by :-
The given points = (5,3) and (8,7)
The distance between theses points will be :
Since , Distance is always positive , it means the distance between the given points is 5 units.
Answer:
3.2
Step-by-step explanation:
The distance formula on a number line is
d= x2-x1
d= 8.7-5.3 =3.2
