Express the inequality −1.8≤x≤−0.03 using interval notation.

[-1.8,0.03]

Step-by-step explanation:

This is how you use interval notation, square brackets means including the numbers, circular brackets means not including

(-1.3,1.8]

Step-by-step explanation:

The inequality −1.3<x≤1.8 means "all numbers between −1.3 and 1.8." In interval notation, we express this as (−1.3,1.8]. Notice that we use a parenthesis to show that the number −1.3 is not included and a bracket to show that the number 1.8 is included.

maximum area = xy = (16)(32) = 512 ft2

to maximize the area of the garden, the side of the fence parallel to the side of the house should be 32 ft long, and the other two sides should both have length 16 ft.'
