Pablo traced along both edges of a ruler to draw two pairs of parallel lines, as shown. What are the next
steps he could take In order to make a conjecture about the diagonals of a parallelogram.
Complete the explanation.
He can use the ruler to draw the diagonals JL and KM, labeling the intersection of these segments as
point .Then he can use the ruler to measure JN, KN, LN, and MN. He will find that JN ?
and KN = ? , leading to the conjecture that the ? 7 of a parallelogram bisect each other.

Use addition and subtraction to simplify the following polynomials. a. add polynomials: (3 – 4x + 8x^2) + (–6 + 2x – 5x^2) step 1: rewrite the polynomials without the parentheses. step 2: write the polynomial in descending order and use parentheses around like terms. step 3: add the like terms identified in step 2 to simplify the polynomial. b. subtract polynomials: (3x – 5 – 7x^2) – (–2 + 6x^2 – 5x) step 1: rewrite the polynomials without the parentheses. remember to multiply each term in the second parentheses by –1. show your work. step 2: write the polynomial in descending order and use parentheses around like terms. step 3: add the like terms identified in step 2 to simplify the polynomial.
