'9' is the constant, because '9' u are adding 9 all the time
x3 + 3x + 5x + 15That's a third-degree expression in 'x'.It can be cleaned up a little bit, by adding the 3x and the 5x. Doing thatdoesn't change anything; it only makes the expression neater:x3 + 8x + 15Now it's a third-degree trinomial in 'x'. If anybody wants to know what numberthe expression is equal to, they'll have to tell you what number 'x' is first. Thevalue of the whole expression depends on the value of 'x', and every time 'x'changes, the value of the expression changes.Notice that it's not an equation, it doesn't ask any question, and it has nosolution or 'answer'. It's just a number, the value of which can be anything.
It's a polynomial of degree 1.
2*10 + 8 = 28
the answer is 110 next time add it up.............idiot!

C++ is a programming language, but, in the same time, it's a valid expression. Example:A= C++is equivalent with:A= C, C= C+1It's a bit of a joke. In the programming language C, ++ is the increment operator, so C++ can be interpreted as "C, except one better."
That all depends on what 'w' is, and every time 'w' changes, the value of your cubic expression is also going to change.
'9' is the constant, because '9' u are adding 9 all the time
if x=-1 and y=3, what is the value of the expression 3x3_2xy?
Oops! That's not an equation. It has no 'equals' sign ( ' = ' ) in it, so it's just an 'expression' that stands for a number. The number that it stands for depends on the value of 'x', and any time 'x' changes, the value of the expression changes.

No
Sometimes you have to take one step backwards to to take two steps forward
Four semiquavers can be played in the time of one crotchet.
Rate = Distance/Time
That's going to depend completely on the value of 'x', and every time 'x' changes, the value of that expression also changes. Whatever 'x' happens to be at the moment, your expression is [ - 2 / (18+x) ].
