yKpoI14uk [10]

Answer:

  100%

Step-by-step explanation:

When the dimensions double, the perimeter doubles.

The percent change can be found from ...

  percent change = ((new value)/(old value) -1) × 100%

Filling in your values, you have ...

  percent change = ((2×(old perimeter))/(old perimeter) -1) × 100%

  = (2 - 1) × 100%

  = 100%

The perimeter increases by 100% from the first garden to the second.

Answer:

Both Carlos and Irene

Step-by-step explanation:

Given the expression (28x - 8)

Carlos : 2(14x - 4)

Danny : 7(4x - 1)

Irene : 4(7x - 2)

The factored expression Given by Carlos, Irene and Danny can be expanded to check if it gives the same expression as that Given in the question :

28x - 7

Irene :

4(7x - 2)

4*7x - 4*2

28x - 8

From.the expanded solutions obtained ;

Both Carlos and Irene's solution corresponds to the factored form of the original equation and are Hence correct
