Pl hell
a) x²y-2xy+y=?
b) ax²+4ax+4a=?
c) 20x-60x²+45x³=?​

a).

b).

c).

the slope of the first function is -3. (3/1)

the slope of the second function is 1. (13-10/6-3).

since |-3| is greater than |1|, the function with the steepest slope is the first.

so the rectangle is 80cm (area)

now to find the area of a triangle.

base times height.

4 times 8.

your answer is 96cm.

hope this .
