6. Tyler is simplifying the expression 6 - 2x + 5 + 4x. Here is his work: 6 - 2x + 5 + 4x
(6 - 2)x + (5 + 4)x
4x + 9x
13x
a.
Tyler's work is incorrect. Explain the error he made.

The line containing the midpoints of the legs of right triangle abc where a(-5,5), b(1, 1), and c(3, 4) are the vertices.

Divide the following fractions 3/4 ÷ 2/3 1/2 8/9 9/8 2

1. 2. ∠b and ∠y are right angles. 3.? 4.? which two statements are missing in steps 3 and 4? ∠x ≅ ∠c △abc ~ △zyx by the sas similarity theorem. ∠b ≅ ∠y △abc ~ △zyx by the sas similarity theorem. = 2 △abc ~ △zyx by the sss similarity theorem. = 2 △abc ~ △zyx by the sss similarity theorem.
