(7b-9)(7b+9)
explanation:
I learned in math last year
Y=4 on the first one
A=92 on the second one
Yes xy(8x2 y - 12xy2 - 7x) is the number you would use for the equation of the formula to figure out the mathematical term you would perhaps use if the values located inside the equation were numerous.
There’s a whole bunch going on i don’t know what to help you with
I’m too lazy to draw a graph but
AB=[2-(-6) , 3-9] = (8,-6)
AB/2 = (8,-6)/2 = (8/2,-6/2) = (4,-3)
mind point of AB is (4,-3) just draw that on a graph and u got it
