Which one of these numbers is a perfect square? 21, 15, 6, 16, 27
Please Answer

16

Step-by-step explanation:

Perfect squares are numbers that can be written as the product of a different number and itself: k * k = k^2.

Looking at the numbers:

21: can be written as 3 * 7, but not in the form k^2

15: can be written as 3 * 5, but not in the form k^2

6: can be written as 2 * 3, but not in the form k^2

16: can be written as 4 * 4, which is in the form of k^2

27: can be written as 3 * 9, but not in the form k^2

Thus, the answer is 16.

Hope this helps!

Step-by-step explanation:

g = (2, 2)

step-by-step explanation:

given the ratio is 1 : 1 then f is the midpoint of eg

let the coordinates of g = (x, y)

using the midpoint formula

(0 + x) = 1 ( multiply both sides by 2 )

0 + x = 2 ⇒ x = 2

similarly

(4 + y) = 3 ( multiply both sides by 2 )

4 + y = 6 ( subtract 4 from both sides )

y = 2

coordinates of g = (2, 2)
