The size of the angle is always corresponding to the opposite side to it, for example
∠A corresponds to side BC
∠C corresponds to side AB
∠B corresponds to side AC
thus given x=6 then:
AC=x^2-x/2=33
AB=x^2+x/2=39
BC=x^2+x/3=34
thus the order of angles from the smallest to the largest is ∠B, ∠A, ∠C
You have to replace the x and y values to the equations in order to determine if they are equal to each other
Answer:
The right answer is : f(-4)=5
Answer:
B.
let the inverse of f(x) be m:
substitute for x in place of m:
It is possible to make 5 equal rows of 4. That covers 20 animals, leaving 2 animals behind. Therefore, there will be 2 animals not in equal rows.
