For long division, you would put 700 in the middle, since the fraction would be 700/21. Then you would figure out how many times 21 goes into 700. Then you would subtract 700 by the amount it would be before it went above 700 by multiplying it by 21. Then, if it is not able to go into 700 fully, you would put a decimal and bring a 0 down.
Answer:
Step-by-step explanation:
Recall that the argument of the square root function y = √x must always be 0 or greater.
If you meant y=√x+8 -7, the domain is therefore [0, infinity).
But if you meant y=√(x+8) -7, the domain is [-8, infinity).
Those parentheses are important!
