Sagot :

Answer

The value of the expression is 486

Step-by-step explanation

Given the expression

2[3(x^2 - 5) + 5y]

To solve this, we will be applying the PEMDAS rule

Where x = 9 and y = 3

Step 1: solve the smaller parenthesis first

2[3(9^2 - 5) + 5*3]

2 [ 3(81 - 5) + 15]

2 [ 3(76) + 15]

2 [ 228 + 15]

Solve the larger parenthesis

2 [ 243] = 486

Hence, the value of the expression is 486
