Here we are given the expression:

Now let us equate it to zero to find x first,

Now subtracting 18 from the other side,

taking square root on both sides,
So we will get two values of x as ,


Now we can write square root -1 as i,
So our factors become,


Answer:
The final factored form becomes,

Half the length of the curve which separates the 2 halves = 1/2 circumference of a circle with diameter 6 mm. = 1/2 * pi * d = 3pi mm
So the length of the line = 6pi = 18.85 mm to nearest hundredth. answer
The area of shaded region = 1/2 area of the circle = 1/2 pi r^2
= 1/2 * pi * 6^2
= 56.55 mm^2 to nearest hundredth answer
The answer is 8n^2
2x2 is 4 x 2 is 8 two n variables so multiple it by 2 and you get your answer
Answer:
33/2
Step-by-step explanation:
6 1/2 ---> 13/2
10 ---> 20/2
13/2 + 20/2 =
33/2
For a question like this, all you have to do is remember that a percentage is simply a fraction expressed as a decimal. So, all we have to do is:

, and then multiply our decimal answer by 100 to get the percentage:

= 0.34
0.34 x 100 = 34
Therefore 34% of the students walk to school.
I hope this helped and remember to please try and understand the maths that got the answer, not just writing the answer down :))
