They have a scale factor of 5:6 so first we need to find the perimeter of KLM:

Then apply the scale factor of 5:6:

Set the denominators equal:

So we see that the perimeter of GHJ is 35.
Answer:
Gregs age is 13
Step-by-step explanation:
13 + 13 = 26
which is equivalent to 13 × 2 = 26
Answer:
C) . y=(1/10)x+3
Step-by-step explanation:
Given the equation of the line is y=-10x+8
It is in the form of y=mx+c where m is the slope of the line. Now on comparision we get m1=-10.
We knoew that two lines are perpendicular iff the product of their slopes is equal to -1.

the slope of the recquired line =
=
The equation of a line is typically written as y=mx+b where m is the slope and b is the y-intercept
Given the y intercept of the recquired line (b)=3
The recquired line is
y=mx+b
y=(1/10)x+3
Well the centroid is the point that connects the median of a side with the opposite vertex. This means that each line is split i half. Notice that line HG is split in half by point K. that means that each of the segments that K splits is equal. so we know
HK = KG
and we know
HK = 3x
KG = x + 8
since
HK = KG then
3x = x + 8
2x = 8
x = 4
now we have x. we know that the each line that runs from a midpoint to a vertex is seperated by the centroid. the 2 line segments are a 2:1 ratio. so
2*JL = 1LG
we know
JL = x + 3
so
2 * (4 + 3) = LG
LG = 14
