Answer:
16
Step-by-step explanation:
It's hard to tell what the what the problem means by "not like the others", but here's a guess.
16 is a perfect square. 16 = 4^2
None of the other numbers are perfect squares.
Also, 16 is not divisible by 3. All other numbers are divisible by 3.

Answer:
(x+6)^2 +(y-4)^2 = 49
Step-by-step explanation:
The equation of a circle is given by
(x-h)^2 +(y-k)^2 = r^2 where (h,k) is the center and r is the radius
(x- -6)^2 +(y-4)^2 = 7^2
(x+6)^2 +(y-4)^2 = 49
Answer:
40 units
Step-by-step explanation:
Given:
Perimeter of ∆ABC = 85 units
AC = 4z
AB = 3z + 3
BC = z + 2
Required:
Numerical value of AC
SOLUTION:
Perimeter of ∆ = sum of all its sides
Perimeter of ∆ABC = AC + AB + BC
85 = 4z + (3z + 3) + (z + 2)
Use this equation to find the value of the variable, z
Collect like terms
Subtract 5 from both sides
Divide both sides by 8
AC = 4z
Plug in the value of x
AC = 4(10)
AC = 40 units
