Răspuns:
150 m
Explicație pas cu pas:
Reamintim:
Perimetrul unui dreptunghi, P
P = 2 (lungime + lățime)
P = 400
Lățime = x
Lungime = 3x
Astfel, avem:
400 = 2 (3x + x)
400 = 2 (4x)
400 = 8x
Împărțiți ambele părți la 8
50 = x
Lungime = 3x
Lungime = 3 * 50
Lungime = 150 m
Answer:
x = 7
Step-by-step explanation:
=> 9/72 = 3x-20/56
=> 9×45/72 = 3x-20
=> 27/3 = x
=> x = 7
Answer:
The rule is x₁ = 2 x₂ = x₁ * 2 x₃ = x₂ + 3 x₄ = x₃ * 2 x₅ = x₄ + 3 ...
Step-by-step explanation:
Unable to use a single equation to define this sequence
The rule is x₁ = 2 x₂ = x₁ * 2 x₃ = x₂ + 3 x₄ = x₃ * 2 x₅ = x₄ + 3 ...
Multiply 2 then Plus 3 then multiply 2 then plus 3 ......
2,4,7,14,17,34, 37, 74, 77, 154....
Answer: c(x) = 2.00 + 0.50x
Step-by-step explanation:
Since they already charged her $2.00 leave that alone. They charge her .50 per night, x represents the number of nights she rented the movie. thus the answer is c(x) = 2.00 + 0.50x.
