P=x+38
add all individual sides together (is also the perimeter):
p=(x+3)+(x-5)+x+(x-2)+(x-4)+(x-1)+(x-1)
=7x-10
set both p equal:
x+38=7x-10
38=6x-10
48=6x
8=x
then insert x=8 in all the side/perimeter equations:
p=x+38=8+38=46
sides:
x=8
x-2=8-2=6
x-1=8-1=7
x-4=8-4=4
x-5=8-5=3
x+3=8+3=11
Answer:
x=5 and x=15
Step-by-step explanation:
3x^2-60x+225=0
3x^2-60x+225/3=0/3
x^2-20x+75=0
x^2-5x-15x+75=0
x(x-5)-15(x-5)=0
(x-5)(x-15)=0
x-5=0 x-15=0
x=5 x=15
Let's take the first derivative:
Notice that we can write this as:
By taking the derivative of both sides 
times, we get:
This means that each time you take a derivative, a factor of 
will appear. So we conclude that:
Taking 
and 
, we get:
So we finally get:
Answer:jsdjjadoji
Step-by-step explanation:
Answer:
Step-by-step explanation:
Plot the center point, C.
angle APC = 68/2 = 34°
angle ACP = 90°-34° = 56°
Arc AB subtends a central angle of 2×56° = 112°
