Jeremy says (x − 9)(x^7 + x^6+x^5 +x^4 +x^3+x^2 +x +1) must equal x^7+x^6 +x^5 +x^4+x^3 +x^2 +x +1 because when x =10, multiplying by x − 9 is the same as multiplying by 1.(a)-multiply (x − 9) (x^7+x^6 +x^5 +x^4+x^3 +x^2 +x +1). (b)- substitute x =10 into your answer. (c)- is the answer to part (b) the same as the value of x^7+x^6 +x^5 +x^4+x^3 +x^2 +x +1 when x = 10? (d) was jeremy right?

Scenario: susan wants to make 2 square flags to sell at a crafts fair. the fabric she wants to buy is 3 meters wide. she doesn't want any fabric left over. what's the least amount of fabric she should buy? question: which equation will susan solve her problem? note: let x represent the length of 1 side of the flag. options: 1) 2x^2 = 4x 2) 8 +2x = 2(4x) 3) 2 * 2 = 4 * 2 4) 4x^2 -2x = 0
