The information is really hard to follow, you should ask the question with a screenshot of the data table.
It would be 9 1/3 divided by 7/1 or 28/3 * 1/7
It would give you 28/21 which would simplify to 4/3 and still leave you with an improper fraction
Evaluate f(9) + f(5)= 14f If I didn't answer Your Question fully than tell me please!
Let us find the co ordinates of each vertex of the triangle .
Vertex A ( in firs second quadrant) = ( -5 ,3)
vertex B in third quadrant = ( -5, -5)
vertex C in fourth quadrant = ( 4, -2)
let us use distance formula AB^2 = ( -5 - 3)^2 + (-5 - -5 )^2 = 64 + 0
AB= 8
BC^2 = ( -2 - -5 )^2 + ( 4 - - 5)^2 = 9 + 81 = 90
BC = 9.48
AC^2 = ( -2 -3)^2 +( 4- -5)^2 = 25 + 81 = 106
AC= 10.29
Perimeter = sum of length of AB+ BC+ Ac = 8 + 10.29 + 9.48= 22.77
