Giving 40 ! solve each given equation and show your work. tell whether it has one solution, an infinite number of solutions, or no solutions, and identify each equation as an identity, a contradiction, or neither. (a) 3x - 5 + x = 2x - 3 + 2 + 2x (b) 4x + 5 - 6x = -x +3 -x +2 (c) 8x + 2 - 6 = 4x +8 +3x

a no solution

b is all real numbers

c x=12

Step-by-step explanation:

a has no values of x that make it true

b any value of x makes it true

c simplify both sides of the equation then isolate x

call the larger triangle abc

then the smaller triangle cde is similar to abc (all angles are equal, aaa).  

ab is the side that is 36, and we wish to find de, the side corresponding to ab

area_cde = area_abc - area_cde --> area_abc / area_cde = 2

let x=length of de

ratio of areas = (ratio of sides)^2
