Answer:
5 perpendicular and 4 parallel line segments so more perpendicular
Perpendicular means "at right angles". A line meeting another at a right angle, or 90° is said to be perpendicular to it. And Parallel Lines or parallel Segments are always the same distance apart, they will never meet. And in this shape there are four parallel line segments and five perpendicular
Answer: 5/12
Step-by-step explanation:
because the denominators are not the same you have to multiply to get a common base and then you can subtract from there to see how much he has left.
The square of the equation 2
– 12x – 20=0 is
What is a quadratic equation?
A quadratic equation is any equation that can be rearranged in standard form as where x represents an unknown, and a, b, and c represent known numbers, where a ≠ 0.
a
+bx+c , a, b, c are integers .
formula: −b±√b2−4ac/2a
Given equation ,
2
-12x-20=0
By comparing with the quadratic equation
Here, a=2, b= -12, c= -20.
X=−b±
/2a
X= -(-12) +
/2(2)
X=12+-
/4
X=12+-
/4,
X=12+- (-4)/4
X=12+(-4)/4 and x=12-(-4)/4
X= 12-4/4 and x=12+4/4
X=8/4 and x= 16/4
X=2 and x= 4
Therefore, the square of the equation 2x2-12x-20=0 is x= 2 and x=4.

They are both correct becuase lets say it was a shirt that was $30 and it was 30% off. For Jasani it would be 30 * 0.7 which equals $9 then you would subtract this 30 - 9 = 21. For Hanna it would be 30 - 0.3(30) which equals $21. So in the end they are both correct!
