if you are given a certain length of wire the biggest area you can fend up is a circle, 2nd a square. For the rectangle to have the biggest area,the difference between the 2 sides must be the minimum, it must approaches a square
then we have 2(l +w) = 200
l + w = 100
the dimensions are 49 & 51
multiply 49 by 51 = 2499 sq. m, will give the biggest area, any other combinations will give a smaller area if you considered decimal numbers between

The two lines will intersect at the point (2, 3).
We can find this by setting the two equations equal to eachother, as the point at which they intersect is the point where they share the same x and y value. First, we have to get both equations in the form y = mx + c, so:
-x - y = -5
+ y
-x = -5 + y
+ 5
y = -x + 5
Now we can set -x + 5 equal to x + 1 and solve to find the x coordinate:
-x + 5 = x + 1
+ x
5 = 2x + 1
- 1
4 = 2x
÷ 2
2 = x
With the x coordinate, we can substitute it in to one of the equations and find our y coordinate:
y = 2 + 1 = 3
So the final answer is (2, 3).
I hope this helps!
-x + 5 = x + 1
Answer:
x = -4y/7 + 51/7
Step-by-step explanation:
First, you add all the numbers without variables and are on the same side.
7x - 4 + 4y + 8 = 55
Then you do the opposite sign (for example the opposite of addition is subtraction) of the two numbers without variables on the left side to add them to the right side(what you do on one side of the equation you must do on the other.
4x - 4 + 4 + 4y + 8 - 8 = 55 + 4 - 8
4x + 4y = 51
Then you get the x by itself by doing the same thing you did with the last step by this time with 4y. Because this has a variable, you don't add it onto the 51, but add as a different number.
4x + 4y - 4y = 51 - 4y
4x = -4y + 51
Now to isolate the x, you divide 4x by 4.
4x/4 = -4y/7 + 51/7
x = -4y/7 + 51/7
Your answer is x = -4y/7 + 51/7
Step-by-step explanation:
3³⁸ - 3³⁷
= 3³⁷(3 - 1)
= 2 * 3³⁷
= 2 / [3^(-37)].
Hence x = -37.
