Answer 1
The value of length and width of the rectangle is L = 28.8 yd , W = 7.2 yd
In the above question, it is given that
Let the length be L and width be W of the given Rectangle
The length of a rectangle is 4yd longer than its width
We can write it in mathematical equation as,
L = 4W ......eqn 1
Also, it is given that, the perimeter of the rectangle is = 72yd
And, we know that, the perimeter of rectangle = 2(L+ W)
72 = 2(L + W)
Putting value of eqn 1 in the above equation, we will get,
72 = 2( 4W + W)
36 = 5W
W = 7.2 yd
Putting the value of W = 7.2yd in eqn 1 we get,
L = 4( 7.2)
L = 28.8 yd
Hence, the value of length and width of the rectangle is L = 28.8 yd , W = 7.2 yd

We use the sum and difference identities.
Remeber the sum difference identity is
[tex] \sin(x + y) = \sin(x) \cos(y) + \cos( x ) \sin(y) [/tex]
and
[tex] \sin(x - y) = \sin(x) \cos(y) - \sin(x) \cos(y) [/tex]

And so on...
Y
-28+16=-12
-12+16=4
4+16=20
And so on...
If this is meant for slope then you would use the formula m=y2-y1/x2-x1
You can use -12 to equal y2 and -21 to equal y1
You can use -3 to equal x2 and -7 to equal x1
Now your equation should be...
m=-12-(-21)/-3-(-7)
m=9/4
9 is the rise
4 is the run
the slope is 9/4
Y-intercept for would be...
m=9/4x

How smart am I from a scale of 1-10?
Answers
Answer:
if you are asking us then probably a... hmmm -_- 3 yes
3 out of 10
Step-by-step explanation:
Answer: we’ll first to find how “smart” you are, we have to verify the level of unsmartness and see if there is any given number. Since the is no given number we will use x as our unknown number. Then we will subtract 1 from 10, therefore giving us the number 9 that we will use in our equation to determine the level of “smart”.
Now we will put 9 and x together:
9x
Now we will find the next part of our equation which will find by looking at how we got the number 9, which is: 10-1
Now we group the parts of this equation which will be:
9x÷10-1
First we will solve one side of our equation
10-1=9
Then we will insert the solved side of the equation
9x÷9
Now we will divide
9/9x
we are left with 1
x=1
Now we insert our solved number back into our previous equation with 1 replacing x
9⋅1÷10-1
Now after we have solved the equation
The answer is: -0.1 will be your level of “smart”

Answer:
[tex]x + 12 \frac{3}{4} = 16 \frac{4}{9} \\ \\ x + \frac{51}{4} = \frac{148}{9} \\ \\ x = \frac{148}{9} - \frac{51}{4} \\ \\ x = \frac{592}{36} - \frac{459}{36} \\ \\ x = \frac{133}{36} \\ \\ \\ x = 3 \frac{25}{36} [/tex]
