Someone pls pls pls : ) the graph of g(x) is the graph of f(x)=x+6 reflected across the x axis which equation describes g? a. g(x)=-x+6 b. g(x)=x-6 c. g(x)=-6x-6 d. g(x)=-x-6

Scenario: a rectangular plot of ground is 5 meters longer than it is wide. its area is 20,000 square meters. question: what equation will you find the dimensions? note: let w represent the width. options: w(w+5)=20,000 w^2=20,000+5 (w(w+5))/2=20,000 w+2(w+5)=20,000
