What is the value of the expression "eight more than three times the difference of four and a number" when n = 3?

Step-by-step explanation:

8+ 3( 4-n) = x

8+ 3*1 = x

x =11

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)
