The perimeter of triangle ABC is 24 units
Step-by-step explanation:
If a segment joining the mid points of two sides of a triangle, then
this segment is:
- Parallel to the third side
- Its length is half the length of the third side
In The triangle XYZ
∵ A is the mid point of XY
∵ B is the mid point of YZ
∴ AB =
XZ
∵ XZ = 18 units
- Substitute the value of XZ in AB
∴ AB =
× 18 = 9 units
∵ B is the mid point of YZ
∵ C is the mid point of XZ
∴ BC =
XY
∵ AY = 7 units
∵ AY =
XY
∴ XY = 2 × AY
∴ XY = 2 × 7
∴ XY = 14 units
∴ BC =
× 14 = 7 units
∵ A is the mid point of XY
∵ C is the mid point of XZ
∴ AC =
YZ
∵ BZ = 8 units
∵ BZ =
YZ
∴ YZ = 2 × BZ
∴ YZ = 2 × 8
∴ YZ = 16 units
∴ AC =
× 16 = 8 units
∵ The perimeter of a triangle = the sum of the lengths of its sides
∴ Perimeter Δ ABC = AB + BC + AC
∴ Perimeter Δ ABC = 9 + 7 + 8 = 24 units
The perimeter of triangle ABC is 24 units

Answer:
Step-by-step explanation:
116f) 5 - |p + 6| = -8
|p + 6| = 13
p + 6 = 13 OR p + 6 = -13
p = 7 OR p = -19
In this case, I think you have to plot a point at 7 and -19.
116a) |7x| = 5
7x = 5 OR 7x = -5
x =
OR x = 
Again, I think you need to plot points at
and
.

Step-by-step explanation:
b is the common denominator
Answer:
x = -2
Step-by-step explanation:
f(x)= 5(x-2)
since, f(x)= -20
-20 = 5(x-2)
x-2 = -20/5
x = - 4 + 2
x = -2
The first one is 25/9
And the second one is 25/36
