The sides of a square are increased by a scale factor of 7 the perimeter of the smaller square is 16 feet. what is the perimeter of the larger square

Perimeter of the smaller square  = 16

That means that one side = 16/4 = 4

That means that the side of the larger square = 4 + 7 = 11

Perimeter of the larger square = 4 * 11 = 44 feet.

b) well because you get well

step-by-step explanation:

we need to solve for 'x' the following equation:  

we have that:

⇒

⇒ ⇒

factorizing, we get that:

  ⇒

then, the solutions are: or
