Answer:

52

Step-by-step explanation:

The ' easiest' method here is to substitute k = 1, 2, 3, 4 into the expression and sum the terms, that is

(- 2 + 6(1) ) + ( - 2 + 6(2) ) + ( - 2 + 6(3) ) + (- 2 + 6(4) )

= (- 2 + 6) + (- 2 + 12) + (- 2 + 18) + (- 2 + 24)

= 4 + 10 + 16 + 22

Given that PS is a median of triangle PQR, find RQ<br> A.6<br> B.12<br> C.19<br> D.38
Zinaida [17]
The median triangle is a line segment that connects the vertex and the midpoint of the opposite side. Therefore, in the given, we can say that RS = QS

Equating RS and QS, we will find the value of X

RS = QS 
5x-11 = 2x+7
5x-2x = 7+11    ⇒ combine like terms
3x = 18             ⇒ divide both sides by 3 to get the x value 
x = 6

Find the value of RS and QS, in this, we will show that two are equal

5(6)-11 = 2(6)+7
19 = 19  ⇒ correct

Therefore RQ is the sum of RS and QS or simply twice the length of either segment

RQ = 19 x 2 = 19 + 19 = 38 (D)
