Hello :)

Answer -

45

Step-by-step explanation -

Our task is to find the value of
\sf{5a^2} when a = -3.

So we replace 'a' with -3:


\begin{gathered}\sf{5(-3)^2}\\\sf{5*9}\\\sf{45}\end{gathered}

Henceforth, the answer is 45.

Answer:

when \(a = -3\), the value of \(5a^2\) is \(45\).

Explanation:

If \(a = -3\), then the value of \(5a^2\) can be calculated as follows:

\[5a^2 = 5 \times (-3)^2 = 5 \times 9 = 45.\]

So, when \(a = -3\), the value of \(5a^2\) is \(45\).
