Circle o is inscribed in triangle rst such that it is tangent at points m, n, and p. if rp is 7, rt is 17 and sm is 5, then what is the length of side st?

  15

Step-by-step explanation:

Tangents to the circle from the same point are the same length. Then rn = 7, and nt = 10. This means mt = 10, so ...

  st = sm +mt = 5 +10

  sm = 15

8

step-by-step explanation:

this is a subtraction problem.

10 - 2 = 8

(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
