PLEASE ANSWER (100points)

When evaluating (6 x + 9) squared minus 5 for x = 1, the given value of 1 is substituted for what part of the expression?
the exponent
the constant
the variable
any numerical value

Answer 1

Variable

• As variable is x and we have to substitute x=1

Explanation:

Let's find the value

`\\ \rm\Rrightarrow (6x+9)^2-5`

`\\ \rm\Rrightarrow (6+9)^2-5`

`\\ \rm\Rrightarrow 14^2-5`

`\\ \rm\Rrightarrow 196-5`

`\\ \rm\Rrightarrow 191`

Answer 2

the variable

Explanation:

Given expression:

`(6x+9)^2-5`

When evaluating the expression for
`x=1`, we need substitute 1 for the variable (
`x`) in the expression.

Evaluating the expression for
`x=1`:

`\implies (6\cdot1+9)^2-5`

`\implies (6+9)^2-5`

`\implies (15)^2-5`

`\implies 225-5`

`\implies 220`
