Answer:
18
Step-by-step explanation:
Adding 6 and 3 gives you the full length of the long side of rectangle and since 3 is the radius of the circle, the short side if the rectangle would also be equal to 3.
So, the long sides equal 9 and the short sides are 3, making the perimeter 18
Answer: -4, 0, 2
Step-by-step explanation:
The graph intersects the x-axis at
.
Vertical angles are where the top equals the bottom or the left equals the right angle. So we would do:
8x - 13 = 5x + 8
And then substitute.
3x = 21
x = 7
For this case we must solve the following quadratic equation:

Where:

The solution is given by:

Substituting:

Thus, we have two roots:
