The pieces are
x,y,z
longest to shortest
y is 5 more than z
y=5+z
z is 8 less than x
z=x-8
find everything in terms of x
y=5+z
sub z=x-8
y=5+x-8
y=x-3
so we got
x=x
y=x-3
z=x-8
total length is 52
x+y+z=52
x+x-3+x-8=52
x+x+x-3-8=52
3x-11=52
add 11 to both sides
3x+11-11=52+11
3x=63
divide both sides by 3
x=21
y=x-3=21-3=18
z=x-8=21-8=13
the pieces are 13in, 18in, 21in
Answer:
<em>a Inferential statistics</em>
Step-by-step explanation:
Inferential statistics are among the two central statistics categories.
<em>To define and draw conclusions about the population, inferential statistics use a random sample of data gathered from a population.</em>
Inferential statistics are useful when it is not feasible or practical to analyze every member of a whole population.

7 1/2 + 15
Answer:
66
Explanation:
Volume for any prism=base area*height
The base is a triangle and the formula to find the area of a triangle is Area=(base*height)/2. Once we input the values it would look like:
Area=(4*3)/2
A=12/2
A=6
In this case, the height of the prism would be 11. Now we input our values for finding the volume:
Volume for any prism=base area*height
Volume=6*11
Volume=66
I hope this helps! Please comment if you have any questions.
