Answer:
11x -8y = -9
Step-by-step explanation:
8x-4y=-4
-3x+4y=5
Subtract the second equation from the first
8x-4y=-4
-(-3x+4y=5)
-----------------------------
Distribute the minus sign
8x-4y=-4
+(3x-4y=-5)
-----------------------------
11x -8y = -9
The maximum area of the rectangular path is when the length is 24 feet and the width is 12 feet.
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables.
Let x represent the length and y represent the width. Hence:
There is 48 feet of fencing:
x + 2y = 48
x = 48 - 2y (1)
The area (A) is:
A = xy = y(48 - 2y)
A = 48y - 2y²
The maximum area is at A' = 0, hence:
48 - 4y = 0
y = 12
x = 48 - 2(12) = 24
The maximum area of the rectangular path is when the length is 24 feet and the width is 12 feet.

Answer:
10,000,000
Step-by-step explanation:
You multiply all of the digits on the bottom starting from right to left with the numbers on the top (Biggest number on top smallest on bottom). after you multiplied 5000 by the first zero in 2000 you go down a line (Lined paper is the best to use) and add a zero as a place holder and then multiply 5000 by the second zero in 2000 then after that you go down a nother line and add two zeros for a place holder... you repeat the steps of multiplying and go down another line and add three zeros as place holders. after your finnished multiplying you add all the numbers in your lines together and you will get 10,000,000
<u><em>Answer: =1024. *The answer must be have positive sign.*</em></u>
Step-by-step explanation:
This question's it's about the order of operations. p-parenthesis, e-exponents, m-multiply, d-divide, a-add, and s-subtract. It can also go left to right.
do exponents first.
16³/2=4098=2048¹/2
2048¹=2048
2048/2
divide left to right.
2048/2=1024
Hope this helps!
Thanks!
Have a great day!
