Roberto has run the first 16 miles of a race, means he is 72% finished. How long is the race?

Let the closed interval [a , b] be the domain of function f. the domain of f(x - 3) is given by (a) the open interval (a , b) (b) the closed interval [a , b] (c) the closed interval [a - 3 , b - 3] (d) the closed interval [a + 3 , b + 3]

What is the value of x in the diagram below?

Xto the second power plus 14x plus 48. what are the factors? we are doing factoring trinomials with a=1
