I need help with this :(

What is the solution to the equation e3x=12? round your answer to the nearest hundredth

Factor the polynomial expression x6 – x3 – 20

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
