Answer 1

Answer:

The Required Expression for the Base Area of the Cubical Suitcase is (3x + 2)²

OR

9x² + 12x + 4

Step-by-step explanation:

Given that the measure of the edge of the Cubical Suitcase is (3x + 2) units

So, Base Area of the Cubical Suitcase is;

>> (Edge)²

>> (3x + 2)²

Using (a + b)² = a² + 2ab + b²

>> (3x)² + 2 * 3x * 2 + 2²

>> 9x² + 12x + 4

Additional Solution for "x" (NOT REQUIRED)

>> 9x² + 12x + 4 = 0

Sum = 12

Product = 9x4 = 36

>> 9x² + 6x + 6x + 4 = 0

>> 3x (3x + 2) +2 (3x + 2) = 0

>> (3x + 2) (3x + 2) = 0

.°. 3x + 2 = 0

>> x = -2/3
