W or the following interpretations for the given expression is correct?

A. The cube of difference between 5 times square of y and 7 divided by The square of 2 times y

Step-by-step explanation:

Given

Required

Interpret

To interpret the given expression, we start by splitting it to two (Numerator and Denominator)

Expand the numerator

Now, we can interpret as follows;

 -> The cube of

 -> The cube of difference between and 7

 -> The cube of difference between 5 * square of y and 7

 -> The cube of difference between 5 times square of y and 7

Similarly;

Interpret

-> The square of 2 * y

-> The square of 2 times y

Bringing the interpretation of the numerator and the denominator, we have;

The cube of difference between 5 times square of y and 7 divided by The square of 2 times y

Hence, option A is correct

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:

x=6 and x=3
