Question

25 POINTS, PLS EXPLAIN! Which sum or difference is modeled by the algebra tiles? Select the correct answer. (-2x + 3) + (3x − 4) (-2x + 3) − (3x − 4) (2x − 3) + (-3x + 4) (2x − 3) − (-3x + 4)

Answer 1

Answer: Consider the expression (2x − 3) − (-3x + 4).

First, distribute the negative sign and rewrite the expression:

2x − 3 + 3x – 4.

Then, model the polynomial.

There are no zero pairs, so the difference is 5x − 7.
