Answer:
The correct answer is d.
Step-by-step explanation:
Let's solve each answer and see which one matches.
Note that in each case, you simply add or subtract from x inside the radical to move left or right respectively. Similarly, just add or subtract to the full expression to move up or down respectively. Doing so we get:
a)
b)
c)
d)
So d is the correct answer.
We are given the following equation and want to find which value of x will make it true:
Subtract 3 from both sides
Divide both sides by -6
Thus, the value that will make 3-6x=21 is x=-3. Let me know if you need any clarifications, thanks!

Answer:
only 2 kid's could go since the price of both is 95 for one and times it by two it's 190
I didn't get all the part with the tiles, but here's the general answer:
given a polynomial
we have that is a factor of if and only if k is a root of , i.e. if
So, given the polynomial
We can check if is a factor by evaluating :
So, is not a factor.
Similarly, we can evaluate to check if are factors:
So, only is a factor of
X= -3
4(-3) = -12
-12-5= -17
