Question

what expression does this set of algebra tiles represent?
combine like terms. for example, write 3 instead of 1 + 1 + 1.

Explanation:

Step1: Count $x^2$ tiles

There are 3 blue $x^2$ tiles, so this term is $3x^2$.

Step2: Count $x$ tiles

There are 2 green $x$ tiles, so this term is $2x$.

Step3: Count constant 1 tiles

Count all yellow 1 tiles: $3 + 2 + 2 + 3 = 10$, so this term is $10$.

Step4: Combine like terms

Add the terms together: $3x^2 + 2x + 10$

Answer:

$3x^2 + 2x + 10$
