Question

Which expression is represented by the phrase "the square of y decreased by the quotient of 28 and 7?

Answer 1

Answer:

$y^2-\frac{28}{7}$.

Step-by-step explanation:

The given phrase is "the square of y decreased by the quotient of 28 and 7".

We need to find the mathematical expression for the given phrase.

Power 2 is used for square.

The sign "/" is used for division or quotient.

The sign "-" is used for subtraction or decrease.

Using these sign we get

Square of y = $y^2$

Quotient of 28 and 7 = $\frac{28}{7}$

The square of y decreased by the quotient of 28 and 7 = $y^2-\frac{28}{7}$

Therefore, the required expression is $y^2-\frac{28}{7}$.

Answer 2

Answer:

$y^{2}-4$

Step-by-step explanation:

We are given the statement,

'The square of y decreased by the quotient of 28 and 7'.

i.e. Subtracting the quotient $\frac{28}{7}$ = 4 from $y^{2}$.

i.e. $y^{2}-4$

Hence, the expression which represents the given statement is $y^{2}-4$.
