1. Make sure you explain why and show all your work. In Triangle QRS, X is the midpoint of QR, Y is the midpoint of RS, and Z is the midpoint of QS.
Also, XR = 5, YS = 7, and QS = 20.
What is the perimeter of the Triangle XYZ?

2. Make sure you show all your work for full points.
What is x?
15
58
Z
X
38

The perimeter is 44.  Because we know the midpoints and distance between the sides of XR is half the side and YS is half the other side, those sides are 10 and 14.  QS is a full side already so it is just 20.  20+14+10=44 for the perimeter.  

Number 2 makes no sense, you've omitted something needed there.

Step-by-step explanation:

they are just trying to trick you... by giving you 1/2 of some of the sides and then the whole side on the last one

QR  +   RS  +  QS = perimeter

2(XR) + 2(YS) + QS = perimeter

2(5) + 2(7)  + 20 = perimeter

10 + 14 + 20 = perimeter

44 = perimeter   :)

step-by-step explanation:

6 + 24 = 30,   so 6/30 = .2  

if you do 1/5 it also equals .2, so that is the answer.

step-by-step explanation:

i think something is missing in your question because y-1=(x-12) would not pass through the point (-4,-3). because if you replace x by -4 your are supposed to find y=-3 which is not the case her. if you replace x by -4 you find =-15.

i assume the right equation is y-1=1/4*(x-12) because this one is passing through both your points (if you are interested to know how i found that out i can tell you).

in this equation if i replace x by -4 i find y=-3 and if i replace x by 12, i find y=1 so the line representing this equation is passing through those 2 points.

then the standard form of the equation is finding an expression of y in function of x

y-1=1/4*(x-12)

y=x/4-3+1

y=x/4-2

hope that .

do you confirm there was a mistake in the question?
