Evaluate the expression y=4. 5+y+8 a)72 b)21 c)17 d)13

C)17

Step-by-step explanation:

5+y+8

let  y=4

5+4+8

9+8

17

175

step-by-step explanation:

2 inches x 10 miles = 200 miles - 3 inches = 175

(f - g)(x) = 5x^3 - 3

step-by-step explanation:

rearrange these functions vertically, with like terms in separate columns:

f(x) = 5x^3 - 2

g(x) =         +1

now subtract, column by column:

(f - g)(x) = 5x^3 - 3
