Which expression is equivalent to 19x − 6x + 2 and why? (1 point)


15x, because 19x − 6x + 2 = 13x + 2 = 15x

11x, because 19x − 6x + 2 = 19x − 8x = 11x

2 + 13x, because (19x − 6x) + 2 = 13x + 2 = 2 + 13x

2 − 13x, because (19x − 6x) + 2 = −13x + 2 =

Answer 1

Answer 2

first one is p+p+p+p+p

Answer 3

last one you have to combine like terms. (first and only step)


like terms are terms whose variables (and their exponents such as the 2 in x2) are the same

what do get from there

Answer 4

the seconded one is 3(3x + 2y) and 9x + 6y
