Answer:
-18
Step-by-step explanation:
-3x + x³
-3(-3) + (-3)³
9 + (-27)
9 - 27 = -18

4-2=2
Answer:
option B
x = 1 + 3√6 or x = 1 - 3√6
Step-by-step explanation:
Given in the question an equation,
3(x-1)² - 162 = 0
rearrange the x terms to the left and constant to the right
3(x-1)² = 162
(x-1)² = 162/3
(x-1)² = 54
Take square root on both sides
√(x-1)² = √54
x - 1 = ±3√6
x = ±3√6 + 1
So we have two values for x
x = 3√6 + 1 OR x = -3√6 + 1
725,278 * 67,066 = 48641494348....now, if x is in the 10 digits spot...it is 4...and if y is in the units spot, then it is 8.....
x + y = 4 + 8 = 12
