O comprimento de um retângulo é 6x e sua largura é 5y. A) Escreva uma expressão algébrica que representa o perímetro desse retân
Kobotan [32]

Answer:

A) 12x + 10y

B) 118cm

Step-by-step explanation:

A) A fórmula para calcular o perímetro de um retângulo é dada como:

Perímetro de um retângulo = 2 (L + W)

= 2L + 2W

Onde

L = comprimento do retângulo

W = largura do retângulo

A) A pergunta nos diz que:

O comprimento de um retângulo é 6x e sua largura é 5y.

A expressão algébrica que representa o perímetro do retângulo =

Perímetro de um retângulo = 2 (L + W)

= 2L + 2W

L = 6x, W = 5y

= 2 (6x) + 2 (5y)

= 12x + 10y

A expressão algébrica que representa o perímetro do retângulo é

P = 12x + 10y

B) Se x = 4 cm e y = 7 cm, qual é o valor numérico desse perímetro.

P = 12x + 10y

x = 4cm

y = 7cm

Perímetro = 12 (4) + 10 (7)

Perímetro = 48cm + 70cm

Perímetro do retângulo = 118cm

Portanto, o valor numérico do perímetro é 118cm

Simplify.
WITCHER [35]

Answer:

20x + 22

Step-by-step explanation:

34- 4x + 12x -12 +12x

step 1: 34 - 12 = 22

now you have left: -4x + 12x +12x

step 2: 12x +12x = 24x

step 3: 24x - 4x = 20x

Now you will combine the two answers you got: 20x +22

Hope this helps :)

One number is 1/4 of another number. The sum of the two numbers is 5. Find the two numbers. Use a comma to separate your answer
masha68 [24]

Answer: 1, 4

Step-by-step explanation:

  • Number #1 = x
  • Number #2 = \frac{1}{4} x

\frac{1}{4} x+x=5\\\\\frac{1}{4} x+\frac{4}{4} x=5\\\\\frac{5}{4} x=5\\\\5x=4*5\\5x=20\\x=4

  • Number #1 = x = 4
  • Number #2 = \frac{1}{4} x = \frac{1}{4} *4=\frac{4}{4} =1
