SOLUTION: the cost of labor for producing x transmissions is L(x) = 0.3x^2 + 400x + 550 dollars, while the cost of materials is M(x) = 0.1x^2 + 50x + 800 dollars. write a polynomial T(x) tha

Question 257333: the cost of labor for producing x transmissions is L(x) = 0.3x^2 + 400x + 550 dollars, while the cost of materials is M(x) = 0.1x^2 + 50x + 800 dollars. write a polynomial T(x) that represents the total cost of materials and labor for producing x transmissions.

Total cost of labor and materials is addition.
So, L(x) + M(x) = T(x). We can express that as

combining like terms gets us
