Add all the digits.
If the sum of digits is a multiple of 3, the number is too
9514 1404 393
Answer:
x < -2 or 3 < x
Step-by-step explanation:
<u>6x -4 > 14</u>
6x > 18 . . . . add 4
x > 3 . . . . . . divide by 6
<u>3x +10 < 4</u>
3x < -6 . . . . subtract 10
x < -2 . . . . . divide by 3
The solution is the union of disjoint sets:
x < -2 or x > 3
These are the steps. Just follow the numbers on the left hand side. Hopes this helps. The answer is -3.
X^3-2x is an algebraic expression. Note that there is NO "=" sign here.
x^4 + 4x^2 + 4 = 0 is an algebraic equation. Note the presence of an "=" sign.
