2.5h + 3.5
This is because it will cost $2.50 for every hour you use, plus an additionally fee for set up

The cost to rent an umbrella for h hours is calculated as 3.50 + 2.50 h , where 3.50 is the setup fee and 2.50 h represents the hourly charge. You can substitute any hour value for h into the equation to get the total cost. For example, if h = 3 , the total cost would be 3.50 + 2.50 × 3 = 10.50 .

Jawaban:cari tentukan hasil perkalian dari (2x + 5y)(3x - 7). Soal: (2x + 5y)(3x - 7) Penyelesaian: Kita akan menggunakan metode distribusi (atau sering disebut metode FOIL jika hanya ada dua suku di masing-masing kurung): 1. Kalikan setiap suku di kurung pertama dengan setiap suku di kurung kedua:- 2x dikalikan dengan 3x: (2x)(3x) = 6x²- 2x dikalikan dengan -7: (2x)(-7) = -14x- 5y dikalikan dengan 3x: (5y)(3x) = 15xy- 5y dikalikan dengan -7: (5y)(-7) = -35y2. Jumlahkan semua hasil perkalian:6x² - 14x + 15xy - 35y Kesimpulan: Hasil perkalian (2x + 5y)(3x - 7) adalah 6x² - 14x + 15xy - 35y
