3. Plantea un sistema de ecuaciones y halla las dimensiones de un rectángulo cuya altura mide 2 cm más que su base y cuyo perímetro es igual a 24 cm. 4. Resuelve por el método de igualación el siguiente sistema de ecuaciones

Height = 5

Width = 7

Step-by-step explanation:

Given that :

Height of rectangle = 2 + Width

Let width = x

Height = x + 2

Perimeter = 24 cm

Perimeter of a rectangle ;

P = 2( height + Width)

P = 24 ; Length = x + 2 ; x

24 = 2(x + 2 + x)

24 = 2(2x + 2)

24 = 4x + 4

24 - 4 = 4x

20 = 4x

x = 5

Height = 5

Width = x + 2 = 5 +2 = 7

answer: 7 x 2/5 = 2.8 hours, is your answer. your welcome! : 3

step-by-step explanation: first work out how long it took to hose 1/7 of the lawn which is 2/5 hours. times that by 7 to get the whole lawn.

sorry i don't know the other answer. i didn't learn what a proportional relationship is.
