Answer:
3 pigs
Step-by-step explanation:
First split the shape into two rectangles to find the area. On the left you can make the rectangle 10*7 and on the right subtract 7 from 16 to get 9 so the one on the right is 9*6. Find the area of both rectangles by multiplying, which will get you 70 and 54 respectively. Add these to get 124 square meters of space in the field. Now you will have to divide it by 36 to see how many pigs can fit, which results in the answer 3.4444... Round down to get 3 pigs as you can not fit another pig in the .4444... of space.

Answers
Answer:
(5, 0 )
Step-by-step explanation:
Given the 2 equations
y = x² - 2x - 15 → (1)
y = 8x - 40 → (2)
Substitute y = x² - 2x - 15 into (2)
x² - 2x - 15 = 8x - 40 ( subtract 8x - 40 from both sides )
x² - 10x + 25 = 0 ← in standard form
(x - 5)² = 0 ← in factored form, thus
x - 5 = 0 ⇒ x = 5
Substitute x = 5 into (2) for corresponding value of y
y = 8(5) - 40 = 40 - 40 = 0
Solution is (5, 0 )

The factor of the equation is (4x – 3) and (3x – 1). Then the solution of the equation will be 3/4 and 1/3.
What is a factorization?
It is a method for dividing a polynomial into pieces that will be multiplied together. At this moment, the polynomial's value will be zero.
The equation is given below.
12x² − 13x + 3 = 0
Then the factor of the equation will be
12x² − 9x – 4x + 3 = 0
3x(4x – 3) – 1 (4x – 3) = 0
(4x – 3)(3x – 1) = 0
x = 3/4, 1/3

Hey!
Hope this helps...
~~~~~~~~~~~~~~~~~~~~~~
What wee need to do, is find what x equals...
12x^2 - 13x + 3 = 0
12x^2 - 13x = -3
12x^2 = 13x - 3
12x = 13 - 3
12x = 10
x = 0.75
Now we check...
12x^2 - 13x + 3 = 0
12(0.75)^2 - 13(0.75) + 3 = 0
12(0.5625) - 9.75 + 3 = 0
6.75 - 9.75 + 3 = 0
-3 + 3 = 0
0 = 0
Here you go!
