Answer: 
Step-by-step explanation:
Given
Perimeter of the rhombus is 
Length of one of the diagonal is 
All the sides of the rhombus are equal
Area of the rhombus with side and one diagonal is
Insert the values
Area with two diagonals length can be given by
Thus, the area of the rhombus is 
and the length of the other diagonal is 
Question 1. -3 + v5 = 0
Work : -3 + 5v = 0
5v = 3 ( divide )
answer v = 3/5
Question 2. 1 - 7B = -20
work : -7b = -20 - 1
-7b = -21 ( divide )
answer b = 3
question 3 : -k - 5 = 0
work : -k = 5
answer : k = - 5
Question 4 : -1 + 8a = 129
work : 8a = 129 + 1
8a = 130 (divide )
answer a = 65/4
D. go study it I dont know it
Answer:
Rewrite the equation as
5
x
+
10
y
=
20
5

10
and simplify.
y=2−x/ 2
Step-by-step explanation:
X=0 bexause the 3s cancel out and your left with 2x=0 so x=0
