PLEASE HURYYY 98 POINTS . Write a polynomial that represents the perimeter of a triangle with side lengths, 4x+5, 10x-5, and 2x+9. (Make sure you have NO spaces in your responses!) (Use ^for your exponent) ( You do not need to use ( ) in your responses!)

The perimeter of a rectangular lot of land is 436 ft. this includes an easement of x feet of uniform width inside the lot on which no building can be done. if the buildable area is 122 ft by 60 ft, determine the width of the easement. select one: a. 9 feet b. 18 feet c. 4.5 feet d. 7 feet

Given sin∅ = 1/3 and 0 < ∅ < π/2 ; find tan2∅ a. (4√2)/9 b. 9/7 c. (4√2)/7 d.7/9

Solve for x. −3/4(x+2)=6 enter your answer in the box
