Use the functions f(x) and g(x) to answer the question. f(x)=x^2+3 ; g(x)=x-7 which expression is equal to (f+g)(x)? a) x^2+x-4 b) 2x^2-4 c) 2x^2+x-4 d) x^2+x+10

step-by-step explanation:

x^2 -12x + 36 + y^2 = 36

x^2 + y^2 = 12x

r^2 = 12rcos(theta)

r = 12 cos(theta)

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
