Answer:
a = 4
Step-by-step explanation:
Assuming you require to find the value of a
In a rhombus all the sides are congruent, thus
9a - 13 = 3a + 11 ( subtract 3a from both sides )
6a - 13 = 11 ( add 13 to both sides )
6a = 24 ( divide both sides by 6 )
a = 4
Then
XW = 9a - 13 = 9(4) - 13 = 36 - 13 = 23
Thus the sides of the rhombus are 23 units
So there's 6 bottles and each bottle costs 3.60 but there's 4 cases.
So first multiply the number of bottles which is 6 with the cases which is 4.
6 x 4 = 24,so there's 24 bottles.Now multiply the price of the bottles time 24.
24 x 3.60 = 86.4.So the person that bought that will have to pay 86.4.Man those things are expensive.
Hope this helps :D
First, you need to find the diameter step by step
Step 1) divide the area by pi
153.86/3.14 = 4
Step 2) get the square root of 49
The square root of 49 is 7, so the radius is 7
Now, find circumference using c =

c=7(3.14)
3.14(7) = 21.98
21.98 square feet is the circumference (fencing)
I hope this helped
