SOLVE THESE TWO FOR PLS

1) D

2) A

Step-by-step explanation: plz mark me brainliest

1) C) 2) B)

Step-by-step explanation:

First one is just times them together get 12root(a^2b^2) = 12ab.

Second question, you use equation 1 to minus equation 2 get 2x = 6, then x = 3, then substitute it into either equation, for example the first one get -7*3 +  5y = 24, then solve for y, can get y = 9, so B) is correct answer.

If it is helpful, plz give me Brainliest.

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)

i do not know this sorry : (
