There are no "of the following" listed, but when you multiply a length by 2/3, you're indicating that you are only "using" 2/3 of that length, which is smaller by a third. Regardless of what your original lengths of the diagonals are, the area is going to be smaller. By 2/3, to be exact.
Answer:
D:21
Step-by-step explanation:
Use the vertical angles equation.
4x + 13 = 5x - 8
Subtract 4x from 5x.
5x - 4x = x
13 = x - 8
Add 8 on both dies.
13 + 8 = 21
x = 21
JKLM has x that equals 21.
<JKLM and <LMJK equal 97 degrees.

Answer:
x = -4 and x = -14
Step-by-step explanation:
Our equation is (x + 9)² = 25
Applying the square root property we would need to take the square root of both sides: 
This give us x + 9 = ±5
Here we have two equations since taking the square root gives us a positive and negative value
Our first equation is x + 9 = 5, and to isolate the variable we would need to subtract 9 from both sides, giving us x = -4
Our second equation is x + 9 = -5, and to isolate the variable we would need to subtract 9 from both sides, giving us x = -14
Answer:
7, 1, -7, -1.
Step-by-step explanation:
5+1/2(14b-8) = -6
5 + 7b - 4 = -6
7b + 1 = -6
7b = -7
b = -1
So, your answer will be 7, 1, -7, -1.
Hope this helps!
