pre algebra answers solved

pre algebra answers solved

--> A part from the algebra is defined as the pre algebra which uses the numbers and letters in problems with simplicity in solving the problems and it is also used in calculating distances. The pre algebra that is used here is contains dissimilar topics. Exponents, linear equations, integers, square roots, and fractions are included in pre algebra. Pre algebra also includes factors which is prime and also the numbers which is prime.
pre solved algebra answers
Problem 1:
Solve:
Find the distance between given points (- 5, -3) and (- 4, -2)
Solution:
To find the distance between points (- 5, - 3) and (- 4, - 2),
Formula:
d=√ [(x2 - x1)2+ (y2 - y1)2]
d = √ [(- 4 + 5) 2 + (- 2 + 3) 2 ]
Solving, we get
d = √ (1+ 1)
= √ 2
After solving, we get
The answer is √ 2.

circumcenter

Let us learn about circumcenter

-->Circumcenter is defined as the point where the three perpendicular bisectors of the sides of the triangle meet. The distance between the vertices of the triangle to the circumcenter is equal.
Importance of learning circumcenter:
Learning circumcenter is important as it is classified as a type of triangle center.
A triangle has an unique circumcenter and it is classified as a type of concurrent point of the triangle.
Circumcenter acts as the center point to draw the circle which is called as circumcircle
