The data found below measure the amounts of greenhouse gas emissions from three types of vehicles. the measurements are in tons per year, expressed as co2 equivalents. use a 0.025 significance level to test the claim that the different types of vehicle have the same mean amount of greenhouse gas emissions. based on the results, does the type of vehicle appear to affect the amount of greenhouse gas emissions?

Need on this one asap im almost done with this subject

Use the distributive law to multiply. 3(4x + 5y + 6)

Agroup of students want to create a garden. they do not know the exact measurements but they propose using a variable to represent the length and width of the garden. the length of the garden is 10 feet longer than double the width. use a single variable to write algebraic expressions for both the length and width of the garden. write an algebraic expression for the area of the garden. use mathematical terms to describe this expression.
