Question

If a = -3, find the value of
2a
a^2
3a^2​

Answer 1

Explanation:

Let's substitute the value of \( a = -3 \) into the expressions:

1. \( 2a \):

\[ 2a = 2(-3) = -6 \]

2. \( a^2 \):

\[ a^2 = (-3)^2 = 9 \]

3. \( 3a^2 \):

\[ 3a^2 = 3(-3)^2 = 3(9) = 27 \]

So, the values are:

\[ 2a = -6 \]

\[ a^2 = 9 \]

\[ 3a^2 = 27 \]
