16(2+5) since when you use distributive property, 16*2= 32 and 16*5= 80
Hello :
let : x = s so : y = x-1
all points is the line passe by : (1, 0) of the slope 1

Actually Welcome to the Concept of the Equilateral Triangles.
Since, we know that, all the sides of a triangle are equal, hence it is a Equilateral triangle.
Equilateral triangle has one all angles equal to 60°.
so, major angle P = 60°
hence, 2x=60°
===> x = 30°
(x+1) x (3x-4) is the answer
