Answer:
The equation in standard form that models area of pumpkins is:
and the area is: 
Step-by-step explanation:
Given that the garden has corn and pumpkins
The expressions are:
Total area of garden: 
Area of Corn: 
Area of Pumpkins: 
The sum of areas of corn and pumpkins is the total area of the garden.
It can be expressed mathematically as:
If we have to find the area of pumpkins,
Putting the values
The equation in standard form that models area of pumpkins is:
and the area is:
The answer is C, when numbers or variables are between "|" (also called bars) it means to remove any negative symbols and think of it as a positive number. If the number is already positive you keep it a positive number.

Answer:
The solution is x = -2, y = -3
Step-by-step explanation:
Let's start with the equation 3x + y = -9
Substitute the y for 5x+7 seen in the second equation
Now you have 3x + (5x+7) = -9
Lets solve:
Let's add the x's
Now we have 8x + 7 = -9
Substracy seven from each side
Now we have 8x = -16
Now let's divide 8 on each side
Now we have x = -2
Now lets plug in -2 to the second equation
The second equation is y = 5x+7
When we plug in -2 we get y=5(-2)+7
We multiply
We now have y = -10+7
Add
y = -3
The solution is x = -2, y = -3
