Consider the expression 16y^2 . Select the correct statement:

tiny-mole [99]

Step-by-step explanation:

Given expression is:

$16y^2$

We will solve each statement one by one to see which statements are correct.

If y=3/4, the values of 16y^2 is 12

Putting y = 3/4 in expression

$16y^2 = 16 *(\frac{3}{4})^2 = 16 * \frac{9}{16} = 9$

If y=1/4, the values of 16y^2 is 2

Putting y = 1/4 in expression

$16y^2 = 16 *(\frac{1}{4})^2 = 16 * \frac{1}{16} = 1$

If y=3/8, the values of 16y^2 is 4/9

Putting y = 3/8 in expression

$16y^2 = 16 *(\frac{3}{8})^2 = 16 * \frac{9}{64} = \frac{9}{4}$

If y=1/8, the values of 16y^2 is 1/4

Putting y = 1/8 in expression

$16y^2 = 16 *(\frac{1}{8})^2 = 16 * \frac{1}{64} = \frac{1}{4}$

If y=2/3, the values of 16y^2 is 3/4

Putting y = 2/3 in expression

$16y^2 = 16 *(\frac{2}{3})^2 = 16 * \frac{4}{9} = \frac{64}{9}$

Hence,

The correct statement is:

If y=1/8, the values of 16y^2 is 1/4
