Answer:
6 and 18 are common because 6x3=18. Remember the rule to multiply all numbers by 3. So multiply 10 by 3 and you will get 30. The total number of square tiles needed is 30 tiles. If you are putting it into a ratio it would be 18:30.
Answer:
stretched by a factor of 2, reflected over the y-axis, and translated 9 units left
Step-by-step explanation:
The given function is 
We can rewrite this function by factoring -4 in the radicand to get:

We further simplify the square root of 4 to get:

The parent function is 
When we compare to the parent function, there is a stretch by a factor of 2, reflection over the y-axis, and translation 9 units left
The last option is correct
Answer:
7890
Step-by-step explanation:
(5000*4%)+(x*5%)=594.50
