Simplify (1+3)2-10÷2
what the solution?

3

Step-by-step explanation:

(1+3)2-10÷2

1+3=4

4x2=8

10÷2=-5

8-5=3

for finding the midpoint of any given 2 pair of points simply add the respective x coordinates with other x coordinate and the y coordinate with other y coordinate and divide them by 2

in your question it will be :

(3+1)/2 for the x coordinate of mid point i.e 2

[8+(-4)]/2 for the y coordinate of midpoint i.e 2

so coordinates of mid point of points (3,8) and (1,-4) will be (2,2)
