Answer:
14n^2.
Step-by-step explanation:
This is Arithmetic with first term a = 14 and common difference d = 28.
Sum of n terms = n/2[2a + (n-1)d]
= n/2(28 +( n -1)28]
= n/2(28 + 28n - 28)
= 14n^2
Answer:
The answer would be X=24
Step-by-step explanation:
Y is multiplied by 3 to get the answer 30. Because they are varied directly you have to multiply the 8 by 3 to get your answer!

Answer:
The value of x is 9 ⇒ C
Step-by-step explanation:
In a circle, if two chords intersected at a point inside it there are four segments created, two in each cord, the products of the lengths of the line segments on each chord are equal.
<em>Let us use this rule to solve the question</em>
In circle H
∵ Jk and LM are chords intersected at point N inside the circle
∴ The created segments are JN, Nk, and LN, NM
→ By using the rule above
∴ JN × NK = LN × NM
∵ JN = x and NK = 2
∵ LN = 3 and NM = 6
→ Substitute these values in the equation above
∴ x × 2 = 3 × 6
∴ 2x = 18
→ Divide both sides by 2 to find x
∴ 
∴ x = 9
∴ The value of x is 9

Answer:
2 feet per year
Step-by-step explanation:
First, we need to find the amount it grew:
13 - 3 = 10
So between 2005 and 2010 it grew 10 feet.
Now to find the yearly growth we need to divide the distance by time:
10 ÷ 5 = 2
So it grew 2 feet per year.
