Evaluate the expression for the given value of x -3 times square root of x-7 when x=121 6 times square root of x+3 when x=100 square root of x/x when x=4 square root of x-17 when x=25

Number 1: square root of 121 is 11

So 11-7= 4 and 4(-3)=-12 x=-12

Number 2: 10 is the square root of 100

So 10+3 is 13 and 13(6) =78 x=78

Number 3: square root of 4 is 2 so substitute x for 2

Giving us 2/2=1 x=1

Number 4: square root of 25 is 5

So 5-17=-12 -12
