Answer: 243

Step-by-step explanation:

We have the expression

3(a + b + c)^2

Note that the expression depends on 3 variables

a, b and c

in this case we want to evaluate the expression for

a = 2\\b = 3\\c = 4

Then change the variable a by the number 2, the variable b by the number 3 and the variable c by the number 4

So we have

3(2 + 3 + 4)^2

Now simplify the expression

3(9)^2

3*81=243

The answer is 243

ANSWER

243

EXPLANATION

The given expression is

3 {(a + b + c)}^{2}

We want to evaluate this expression for:

a = 2, b = 3, and c = 4.

We substitute the given values into the expression to get:

3(2 + 3 + 4)^{2}

Let us perform the addition inside the parenthesis to get:

3(9)^{2}

3(81) =24 3

Therefore the given expression evaluates to:
