Answer:
42
Step-by-step explanation:
3(x+x+6)=270
3(2x+6)=270
6x+18=270
6x=252
x=42
I believe it’s C, because in a recursive rule you must have (n-1), this shows that you’re using the previous term to solve for the next one.
Answer:
Step-by-step explanation:
The current equation of the circle is:
⇒
In order to get it into the standard form;
⇒
We must complete the square;
⇒
Now, collect like terms and rearrange;
⇒
We now know that the Centre is at the point (2, 1).
We can use the distance formula to find the radius;
⇒
⇒
⇒
Therefore the radius squared is 17.
Now substitute into our equation:
⇒
It is a similar triangle so the side length of the smaller triangle (x and x-2) are in the same ratio as the bigger triangle (2x+5 and 2x-1). As the ratio is the same, you can equate them and solve for x.
