But the item asks for a multiplication equation that Andy <em>could</em> have written using ? for the # of rows. From that instruction, this is acceptable: ? x 1 = ? And so is <em>y</em> x ? = 56 <br />I doubt that is what the item writers want, but that is in the range of what they asked for.C.L.

If you form the equation, it isn't quadratic. It's cubic, meaning that there ought to be three solutions. The third, of course, is negative, thus falling outside of the specified domain and outside of the graph.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-6172532982347376290.post-9814565664991341172013-11-12T13:24:10.840-05:002013-11-12T13:24:10.840-05:00The item for 3rd grade on the PARCC website has ch...The item for 3rd grade on the PARCC website has changed cards to tiles in Part A.Anonymousnoreply@blogger.com
