Aditi is participating in a walkathon fundraiser. Two anonymous donors agree to donate money according to the distance she walks. The money, A, in dollars, that she receives from the first donor for walking d kilometers is given by the formula A(d)=12d. The total money, T, in dollars, that she receives from both donors for walking d kilometers is given by the formula T(d)=d^2+20d

A(d) + B(d)

12d+d^2

Step-by-step explanation:

it wants the total money so you add 10d and 2d but you can't add d^2 because it has an exponent and its the only one that has one

Step-by-step explanation:

B(d)=T(d)-A(d)

D^2+8d

for this pair of functions g(x)=x-2 and f(x)=|x| is (g o f)(a)= |a| -2

step-by-step explanation:

g(x)=x-2

f(x)=|x|

(g o f)(a)=?

(g o f)(x)=g(f(x))

(g o f)(x)=g(|x|)

(g o f)(x)=|x|-2

(g o f)(a)=|a|-2
