Couple different ways to approach this
If all sides are equal you would just add 4 twice, 72 + 8=80, now divide by 4, 20 is the length, width is 4 less than length so subtract 4, 16 is width, now add 2 lengths and 2 widths to double check, 20 + 20 + 16 + 16=72
You look at what the question says carefully and then you put that into the answer
The slope of the line = (2- -8) / (3 - - 5) = 10 / 8
= 5/4
y - y1 = m(x - x1) where m = slope and (x1, y1) is a point on the line so here we have:-
y - 2 = 5/4(x - 3)
y = 5/4x - 15/4 + 2
y = 5/4 x - 7/4 is the answer
Every number is getting X2 after the number, the next number will be 62
