If (3a+ 3/a )=5, what is the value of 9a^2+ 9/a^2
urgent

  7

Step-by-step explanation:

Squaring the first equation gives ...

  9a^2 + 2·3a·3/a + 9/a^2 = 25

The factors of "a" in the middle term cancel, leaving ...

  9a^2 +9/a^2 +18 = 25

Subtracting 18 answers the question:

  9a^2 +9/a^2 = 7

The value for the given expression:

First, we need to square both the sides of the given expression:

On applying the below algebraic identity:

We get,

On squaring the terms:

On cancelling the ‘a’ variable:

On multiplying the constants:

On taking constant on one side and keeping variable on one side:

On subtracting the constants, we get the final answer as:

image result for what is another name for consecutive interior angles? ​

when two lines are crossed by another line (called the transversal): the pairs of angles on one side of the transversal but inside the two lines are called consecutive interior angles. in this example, these are consecutive interior angles: d and f.
