Arectangular lawn sits behind a large house. rectangle , whose coordinates are (−75,100), (−100,0), (100, −50) and (125,50) models the lawn. each unit represents 1 foot. ana is going to overseed the existing lawn. according to the instructions on the lawn seed she is using, she should overseed at a rate of 1.5 pounds per 1,000 square feet. how much seed should ana use for this lawn to the nearest pound?

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.

Fractions can be added and subtracted only if they're fractions. a. like b. proper c. improper d. unlike
