Which of the following is the product of the rational expressions shown below? x+3/x+2•x-3/x-2 A. 9/4 B. x^2-9/x^2-4 C. x^2/x^2-4. D. x^2-4/x^2-9

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.

h * s * a

h = history teacher

s = science teacher

a =   art teacher.

i see no data table, but just multiply the number of history teachers, science teachers, and art teachers.

your answer is  

d.
