Which are perfect squares? check all that apply. 72 36 8 16 81 64 48

Answer : The perfect squares are, 36, 16, 81 and 64

Step-by-step explanation :

Perfect square : It is a number made by squaring a whole number.

For example:

2 × 2 = 2² = 4

So, 4 is a perfect square.

3 × 3 = 3² = 9

So, 9 is a perfect square.

4 × 4 = 4² = 16

So, 16 is a perfect square.

5 × 5 = 5² = 25

So, 25 is a perfect square.

6 × 6 = 6² = 36

So, 36 is a perfect square.

7 × 7 = 7² = 49

So, 49 is a perfect square.

8 × 8 = 8² = 64

So, 64 is a perfect square.

9 × 9 = 9² = 81

So, 81 is a perfect square.

and so on

Hence, from the given numbers we conclude that 36, 16, 81 and 64 are perfect squares.

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

answer:

f(5/2) = 10/3

i hope this you!
