Simplify the first expression 5 (m + 1) -1​

5m+4

Step-by-step explanation:

(5m)+5(1)-1

5m+5-1

5m+4

Step-by-step explanation:

You basically do the distribution property with the 5(m+1)= 5(m)+5(1)-1

5m+5 - 1

5m+4

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)
