Answer:
0.124
Step-by-step explanation:
To divide the numbers, we need to remove the decimal point
To remove decimal point , we multiply top and bottom by 100
Use long division. After using decimal point at the top we can include any number of zeros with 719
. 1 2 3 9

Division goes on ............
Estimate the quotient to 3 decimal places
Quotient = 0.124
The radical equation is 
.
i) We first isolate the square root, adding 5 to both sides of the equation:
ii) Here let's substitute x+6 with t. Doing so we have:
Squaring both sides, we get:
iii) Collecting the variables on the same side, and factorizing t we have:
, which yields
t=0 or t=1.
Now we solve for x in x+6=t:
x+6=0 ⇒x=-6 and x+6=1⇒x=-5.
iv) Now we check these values in the original equation
:
a)
⇒ 0=0 ; Correct.
b)
⇒ 1=1 ; Correct.
