Tawanna is asked to find the GCF of each term in the expression 2 a b + 8 b. Her work is shown below. Factors of 2ab: 1, 2, a, and b Factors of 8b: 1, 2, 4, 8, and b GCF: (1) (1) (2) (2) (b) (b) Which best describes the error in Tawanna’s solution? Tawanna factored one or both pieces of the expression incorrectly. Tawanna did not include each factor in the GCF. Tawanna should have used each common factor once. Tawanna included only one of the variables in her solution.

step-by-step explanation:

ok so im not 100% sure but you would start by adding 5.1t and 1.9t beacuse they have the same variable. that is 7t.   then add -3.6 + 1.2 which is -2.4

so then keep that as -2.4 + 7t. i apologize if this is incorrect. best luck on your test < 3

compare the two slopes in the decimal form. if the slopes are equal, then the lines are parallel. if the slopes are not equal, then the lines are not parallel.
