Answer:
The number of counties in state A are 70.
The number of counties in state B are 68.
Step-by-step explanation:
The number of counties in state A and the number of counties in state B are consecutive even integers whose sum is 138.
Let the two consecutive even integers be x and x+2.
As their sum is 138, we can denote this mathematically as :
Now, we get x = 68
And = 70
Hence, the two numbers are 68 and 70.
So, the number of counties in state A are 70.
The number of counties in state B are 68.
Answer:
LK = 4
Step-by-step explanation:
given point J (4, 4 )
then LJ = 4 and JK = 4
using Pythagoras' identity in right triangle LJK
LK² = LJ² + JK² = 4² + 4² = 16 + 16 = 32 ( take square root of both sides )
LK = =
=
×
= 4
