Since you want help i wont tell you the answer..just how to solve...
(need to know) Of in math means multiply
they are giving you something to plug in to f(x) so everywhere in the equation there is an X replace with the equation and solve....in this case they are replacing f(x) with f(a+2) so take 3+x and change it to 3+a+2 and then take x-3 and make it a+2-3.
Then you have 3+a+2 divided by a+2-3

Step-by-step explanation:
Side a = 63
Side b = 21
Side c = 66.40783 = 21√10
Angle ∠A = 71.565° = 71°33'54" = 1.24905 rad
Angle ∠B = 18.435° = 18°26'6" = 0.32175 rad
Angle ∠C = 90° = 1.5708 rad = π/2Area = 661.5
Perimeter p = 150.40783
Semiperimeter s = 75.20392
Height ha = 21
Height hb = 63
Height hc = 19.92235
Median ma = 37.85829
Median mb = 63.86901
Median mc = 33.20392
Inradius r = 8.79608
Circumradius R = 33.20392
Vertex coordinates: A[0, 0] B[66.40783, 0] C[6.64078, 19.92235]
Centroid: [24.34954, 6.64078]
Inscribed Circle Center: [12.20392, 8.79608]
Circumscribed Circle Center: [33.20392, 0]
Answer:
your total bill will be 7.37
Step-by-step explanation:
The questions is an addition problem so
3.17 + 1.45 + 2.75 = 7.37
