\large \bold {ANSWER}

\implies \boxed{\underline{\huge{\tt{\orange{\: \: c)15 \: \: }}}}}

\large \bold {SOLUTION}

Having substituted the values of "x" and "a" in the algebraic expression, 15 was obtained as a numerical value.

To obtain the numerical value of the algebraic expression,

one must substitute in the same, the values of "x" and "a" respectively.

\begin{gathered}5x + a^2 - x^2\\\\5.2 + 3^2 - 2^2\\\\10 + 9 - 4\\\\19 - 4\\\\15 \\\end{gathered}

MAVERICK [17]
Imagine you have 4 'slots' on the stage:
_ _ _ _

In the first one there can be 1 out of 9 performers.
In the second - 1 out of 8 (because one has been already chosen).
In the third - 1 out of 7 (because two have been selected).
In the forth - 1 out of 6 (because three are already on the stage).

Total number of combinations is equal to: 9x8x7x6 = 3024

So the correct answer is D.

Hope it helps!
