Prove part 2: If the diagonals of a trapezoid are congruent, then the trapezoid is isosceles. Given: ABCD is a trapezoid with line BC ∥ line AD and diagonals line AC ≅ line DB . Prove: ABCD is an isosceles trapezoid.

you ignore the remainder, therefore the answer is y = x+2

step-by-step explanation:

you have to divide the denominator by the numerator. you can use synthetic division or long division.

[-5] .     1 .     7 .     11

x + 2 + 1/x+5
