Answer: C
Step-by-step explanation:
Since this is an isosceles triangle as indicated by the markers on QP and PR, we know that QS and SR are equivalent.
To find the value of n, we set QS and SR equal to each other.
6n+3=4n+11 [combine like terms]
2n=8 [divide both sides by 2]
n=4
Now that we know n=4, we know that A is incorrect. What we can do is use the value of n to solve for QS, SR, and QR.
QS
6(4)+3=13
Since the length of QS is 13, we know B is incorrect.
SR
4(4)+11=27
Since SR is 27, C is a correct answer.
QR
13+27=40
Since QR is 40, the only correct answer is C.

I'm not sure if this is the answer you were looking for, apologies if it isn't.
Let's solve for x.
xxy−5z=−68
Step 1: Add 5z to both sides.
x2y−5z+5z=−68+5z
x2y=5z−68
Step 2: Divide both sides by y.
x2yy=5z−68y
x2=5z−68y
Step 3: Take square root.
x=√5z−68y or x=−√5z−68y
Answer:
x=√5z−68y or x=−√5z−68y
Let's solve for x.
2x−y+3z=19
Step 1: Add y to both sides.
2x−y+3z+y=19+y
2x+3z=y+19
Step 2: Add -3z to both sides.
2x+3z+−3z=y+19+−3z
2x=y−3z+19
Step 3: Divide both sides by 2.
2x2=y−3z+192
x=12y+−32z+192
Answer:
x=12y+−32z+192
Let's solve for x.
x−2y+2z=−15
Step 1: Add 2y to both sides.
x−2y+2z+2y=−15+2y
x+2z=2y−15
Step 2: Add -2z to both sides.
x+2z+−2z=2y−15+−2z
x=2y−2z−15
Answer:
x=2y−2z−15
