Answer:
"Evaluation" mostly means "simplifying an expression down to a single numerical value". Sometimes you will be given a numerical expression, where all you have to do is simplify; that is more of an order-of-operations kind of question
example: So let we are given a polynomial function as:
and we are aksed to evaluate this polynomial at
Then the value of the polynomial will be:
Hence on evaluating the polynomial function f(x) at we get the value of the polynomial function as .
The volume will decrease.
If everything else remains the same then it will decrease. If other sides were increased proportionally then it would stay the same. It would increase if other sides were enlarged more than the length was shortened.
If you are solving for b:
-2.6b+4=0.9b-17 <subtract 4 from both sides
-4 -4
-2.6b =0.9b-21 <subtract 0.9b from both sides
-0.9b -0.9b
-3.5b = -21 <divide by -3.5
--------- ------
-3.5 -3.5
b=6
