Concept explainers
Explain how algebra tiles represent like terms and zero pairs.
Explanation of Solution
Concept Used:
Algebra tiles are square and rectangle shaped tiles or tiles that represent numbers and variables. For example, we can use square tiles to represent numbers. Each square tile is equal to one.So, four can be represented by four square tiles.
For like terms we need to colour each tiles with same colour
Zero Pairs
A zero pair is a pair of numbers that, when added together, equal zero. ... So, this means that '1' and '-1' are a zero pair - when added together, they equal zero and the positive cancels out the negative.
When one adds positive like terms to negative like terms using algebra tiles, they need to bring in the idea of "elimination" or "zero pairs" every time they add a positive one to a negative one.
This is true for any number of tiles, as the same like terms with opposite sign eliminate each other (or create a zero pair).

- Trolley of the overhead crane moves along the bridge rail. The trolley position is measured from the center of the bridge rail (x = 0) is given by x(t) = 0.5t^3-6t^2+19.5t-14 : 0 <= t <= 3 min. The trolley moves from point A to B in the forward direction, B to C in the reverse direction and C to D again in the forward direction.
