anonymous · Answer

and above it says "suppose that (x in a triangle) means x+5, (x in a square) means x^2, and (x in a circle) means 2x-3."

anonymous · Answer

is the 4 an x?

anonymous · Answer

in the triangle it is a four, thats what the diagram says

anonymous · Answer

x+5 +x^2 +2x-3 =x^2+3x+2=(x+2)(x+1) now put in 4 for x

anonymous · Answer

so basically your just adding them altogether in an equation, and then substituting for x?

phi · Answer

x in triangle, with x=4 gives 9 in circle.  9 in circle is 2*9-3 = 15
15 in square is 15*15 = 225
