If 3x + 5 = 15, what is the value of the expression (3x + 2)(3x + 3)(3x + 4)?

3x + 5 = 15 Subtract 5 from both sides.
3x = 10 Divide by 3
x = 10/3

3x + 2 = 3*10/3 + 2 = 10 + 2 = 12
3x + 3 = 3*10/3 + 3 = 10 + 3 = 13
3x + 4 = 3*10/3 + 4 = 10 + 4 = 14

Therefore there answer = 12 * 13 * 14 = 2184
The three numbers multiplied together = 2184
2184 <<<< answer

Step-by-step explanation:

g(x) = 3x + 5

g(3) = 3(3) + 5

g(3) = 9 + 5

g(3) = 14

f(x) = 2x² + 3

f(g(3)) = 2(g(3)) + 3

f(14) = 2(14²) + 3

f(14) = 2(196) + 3

f(14) = 392 + 3

f(14) = 395

f(g(3)) = 395
