It is helpful to become familiar with the rules for secants of a circle.
The product of the numbers on the same chord is the same.
.. 2*x = 5*8
.. x = 20

The picture is not drawn to scale. (They almost never are.)
I'm guessing you are asking what a number raised to the third power would be called, in that case it'd be called cubed :)
Do 720 divided by 90 and then draw 7 100 base blocks 2 ten blocks and tjen divide 9 10 blocks! hope that helped
Answer:
-(-5) ± √13 5 ± √13
x = ----------------------- = ---------------
2(3) 6
Step-by-step explanation:
This is a quadratic equation, with coefficients 3, -5 and 1.
The discriminant, b² - 4ac, turns out to be (-5)² - 4(3)(1), or 25 - 12 = 13
Thus, the roots are:
-(-5) ± √13 5 ± √13
x = ----------------------- = ---------------
2(3) 6
Answer: y = -x - 1
<u>Step-by-step explanation:</u>
Use the Point-Slope formula: 
where
- (x₁ , y₁) is the given point (0, -1)
Insert those values into the formula and solve for y:
y - (-1) = -1(x - 0)
y + 1 = -x
y = -x - 1
