what expression does this set of algebra tiles represent?\ncombine like terms. for example, write 3 instead of 1 + 1 + 1.
Answer
Explanation:
Step1: Count the number of (x) tiles
There are (3) (x) tiles. So the term for (x) is (3x).
Step2: Count the positive unit tiles
There are (2) positive unit tiles. So the positive - unit - term is (+ 2).
Step3: Count the negative unit tiles
There are (7) negative unit tiles. So the negative - unit - term is (-7).
Step4: Combine like terms (unit terms)
[2+( - 7)=2 - 7=-5]
Answer:
(3x - 5)
