Answer:
length = 11 , width = 18
Step-by-step explanation:
Begin by letting x represent the width.
then double the width = 2x and 5 less than this = 2x-5
meaning the length is 2x - 5
now perimeter = 2x width + 2 x length
therefore 2x + 2(2x - 5) = 38
so 2x + 4x - 10 = 38
⇒ 6l = 38 + 10 = 48 ⇒ l = 8
width = x = 8cm and length = 2x - 5 = 16 - 5 = 11cm
check check: (
2 x 8
) + (
2 x 11
) = 16 + 22 = 38

I do not know the rest, sorry.
Hope I helped!

Given that,
KM bisects ∠LKJ.
m∠LKM = 4x + 12 and m∠MKJ = 6x - 6
To find,
The value of x.
Solution,
As KM bisects ∠LKJ. It would mean that,
m∠LKM = m∠MKJ
Putting the above values,
4x+12=6x-6
We can solve the above equations as follows :
4x-6x=-12-6
-2x=-18
x=9
Therefore, the value of x is equal to 9.
Answer:
+ 
= 4 + 4 * 3 = 16 = 
Step-by-step explanation:
The Pythagorean Theorem states that the two shorter sides of a right triangle squared and added together will equal the longest side (hypotenuse) of the right triangle squared. The longest side of this right triangle is 4, 4 squared is 16. The two shorter sides of the right triangle are 2 and 
, squared individually would be 4 and 12, and added together they also equal 16. These sides are a valid input for the Pythagorean Theorem, so these three sides are the sides of a right triangle. 2 and being the legs of the right triangle, and 4 being the hypotenuse.
