For 3(x-2) = 30+x - 2 - x + 2, does x=12?

True

Step-by-step explanation:

Substitute x=12 into the equation, if left side = right side, x = 12

3 (x - 2) = 30 + x - 2 - x + 2

3 ((12)-2) = 30 + (12) - 2 - (12) + 2

3 (10) = 30 - 2 + 2

30 = 30

Left side = Right side

Therefore, x = 12

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)

answer: 25 is the correct answer
