Answer:


Step-by-step explanation:
Given a parallelogram ABCD is shown with DC equal to 9 feet and the perpendicular distance between AB and DC equal to 8 over 9 foot.
Part A: we have to find the area of ABCD.



Part B:
We have to decompose this parallelogram into two triangles.
Join diagonal AC
As the diagonal of parallelogram divides it into two congruent triangles of equal area
Hence, the area of each triangle is


You will need to add 3 to each side.
x^2-3=15
+3 +3
x^2=12
and go from there
The important information's already given in the question can be used to find the correct answer.
In 1 hour Ursula earns = 9 dollars
So
In h hours Ursula earns = (9/1) * h dollars
= 9 * h hours
= 9h hours
So we have found from the above discussion that Sarah wrote the correct answer and it was 9h.
I hope you are satisfi3ed with the answer and the
explanation that I have provided. You can use this procedure for solving

Answer:
y = (-3/2)x + 1/2
Step-by-step explanation:
Note that slope intercept form = y = mx + b
Change the given equation so it matches the form:
3x + 2y = 1
Isolate the variable, y. Note the equal sign, what you do to one side, you do to the other. First, subtract 3x from both sides:
3x (-3x) + 2y = 1 (-3x)
2y = -3x + 1
Next, Divide 2 from both sides:
(2y)/2 = (-3x + 1)/2
y = (-3/2)x + 1/2
y = (-3/2)x + 1/2 is your answer.

Answer:
1/3n-3<6
Step-by-step explanation:
One third of a number: 1/3
3 is subtracted from 1/3 of a number n: 1/3n -3
Result is less than 6: less is represented with the symbol <. So, the result of the expression 1/3n-3 is less (<) than 6.
The final expression:
1/3n-3<6
