The answer to this question:
<span>north and south sides 16ft
east and west sides 8ft
</span>
In this question, the east and west fencing cost is $4/ft but the south and north fencing cost is $2/ft. The cost is cheaper for fencing north and south side which cost half of the east and west side. The perimeter is made by adding the south, north, east and west side.
If x = north and south fencing and y= is east and west side, then you can get this equation
cost= (south+north) * $2 + (east+west)*$4
128=(x+x) * 2 + (y+ y) * 4
128= 4x + 8y
32= x+ 2y
x= 32-2y
The area is count by multiplying the width and length, which was x and y in this question. The formula should be:
area= length * width
area= x * y
area= (32-2y) * y
area= 32y - 2y^2
Then, you need to find the value of y needed for the maximum area.
32y- 2y^2
32 - 2*2y=0
32= 4y
y= 8
If y=8 then
x= 32-2y
x= 32- 16= 16
This problem calls for application of the distributive rule for multiplication.

There are four possibilities...but first does the problem tell you how many total fish were sold?
If not the possible combinations are:
0 angel and 9 clownfish
2 angel and 6 clownfish
4 angel and 3 clownfish
6 angel and 0 clownfish
Answer:
OPtion C: 48
Step-by-step explanation:
Given that:
Each table has = 8 chairs
Total pieces = 54
So the chairs are:
8x + 8 = 54
8x = 48
x = 48/8
x = 6
There are 6 table and 48 chairs
i hope it will help you!
Answer:
x = 2.25 (Approximately)
Step-by-step explanation:
4 + 3x^4 = 81
4 - 4 + 3x^4 = 81 - 4
3x^4 = 77
(3x^4)/3 = 77/3
x^4 = 25.67 (Approximately)
x = 2.25 (Approximately)
