A right triangle has an area of 9 square feet. It was dilated to a similar right triangle with an area 4 times the size. What scale factor was used to dilate the triangle?

  n=   0.0000 - 0.3750 i  

  n=   0.0000 + 0.3750 i

step-by-step explanation:

one of these should be correct

the volume is the product of the area of the base, 3x(3x+4), and the height, 3x-1

step-by-step explanation:

or

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
