Ans : 1m =100cm
so 18.386m =1838.6 cm
2.9n+1.7-(1.7)=3.5-(1.7)+2.3n === 2.9n-(2.3n)=1.8+2.3n-(2.3n) === .6n/.6=1.8/.6 === n=3 :)
Answer:
P' = 1/3 P
reflection in the y-axis just changes the sign of all the x-values.
Since P" ≅ P', and P' is smaller than P, P" cannot be ≅ to P
It is, however, similar to P.
Integers are
-4,-3,-2,-1,0,1,2,3,4...
-24 is an integer
ratinoal is numbers that can be written in a/b
-24=-24/1
it is a rational number
whole numbers are
0,1,2,3,4,5
no negatives
not a whole number
it is in integer and rational
