Answer:
Then what is the radius of the circle? Since, the tangent of any point of a line is perpendicular to the radius through the point of contact. Hence, radius of the circle = 8 cm.
X is 20 because 20/5 is 4 n 4+1=5
At age 6, he read six. That doubled would be 12 books. So at age 7, he read 12. 12 doubled is 24. At age 8, he read 24. That doubled would be 48. At age 9, he read 48. That double would be 96. So by age 10, he would have read 96 books.
Answer:
n² + 3n +1
Step-by-step explanation:
n(n+1) + 2n + 1
<h3>i) distribute n into the parantheses</h3>
= (n×n) + (n×1) + 2n + 1
= n² + n + 2n + 1
<h3>ii) collect like terms</h3>
= n² + 3n +1
The answer above is most likely B. Subtract 395 from 360 to get 35. 360 is a full circle which is why you subtract it.
