Bonjour j’aurais besoin d’aide pour cet exercise (le numéro 20). J’aurais besoin d’une réponse le plus tôt possible! Merci

Timed***how else can the sequence for row 1 be written? notice: square a: 1 penny = 20 square b: 2 pennies = 21 square c: 4 pennies = 22 the sequence formed is geometric, with a1 = , and common ratio r = .

Which shows the correct substitution of the values a,b and c from the equation 1=-2x+3x^2+1

Complete the solution of the equation. find the value of y when x equals to 1 9x-5y=29
