A square has sides of length x. If the sides are all tripled in length, the perimeter of the square is multiplied by

Lets just assume that each side length of the triangle is 4 inches.

To find the perimeter we can multiply one side by 4: 4 * 4 = 16in. (perimeter)

Now, if each side was tripled (4 * 3 = 12) the perimeter will be different. The perimeter of this new square is: 12 * 4 = 48in.

Finally, divide by the old perimeter to see how much the perimeter was multiplied by.

48 / 16 = 3

Therefore, the perimeter was multiplied by 3.

Best of Luck!

solution:

the given function is ,

      =

the three roots of this quadratic function is , 0 ,8 and 10.all the roots are real and rational.

if a quadratic equation is of the form ,

sum of the roots = a + b +c= 0+8+10=18=  

product of roots taken two at a time = a b + b c+ c a = 0+80+0=80 =  

product of roots = a b c = 0=  

there are 11 doors in a hall starting from 0 to 11.the entry in the hall is permitted through gate number 0 and exit is allowed through only gate number 8 and 10.so, three roots(0,8,10) of quadratic function is given by entry and exit route of this hall.
