7 x 2 = 14
3 x 1 = 3
14+3 = 17
answer 17 unit^2
Answer:
1.
Part A: Yes, it is (a - b)².
Part B: a² - 2ab + b² => (x - 6)² = x² - 12x + 36.
Part C: x² - 12x + 36.
2.
Part A: Not a special product.
Part B: Binomial distribution => (x + 8)(x + 1) = x² + 9x + 8.
Part C: x² + 9x + 8.
3.
Part A: Yes, it is (a + b)²
Part B: a² + 2ab + b² => (3x + 2)² = 9x² + 12x + 4.
Part C: 9x² + 12x + 4.
4.
Part A: Yes, it is (a + b)(a - b), a difference of squares.
Part B: a² - b² => 4x² - 49
Part C: 4x² - 49.
5.
Part A: Not a special product.
Part B: Binomial distribution => (x - 5)(2x - 5) = 2x² - 15x + 25.
Part C: 2x² - 15x + 25.

The line integral along the given positively oriented curve is mathematically given as
This is further explained below.
<h3>What is the line integral along the given positively oriented curve.?</h3>
Generally,
![\int M d x+N d y=\iint\left(\frac{\partial N}{\partial x}-\frac{\partial M}{2 y}\right) d y d x](https://tex.z-dn.net/?f=%5Cint%20M%20d%20x%2BN%20d%20y%3D%5Ciint%5Cleft%28%5Cfrac%7B%5Cpartial%20N%7D%7B%5Cpartial%20x%7D-%5Cfrac%7B%5Cpartial%20M%7D%7B2%20y%7D%5Cright%29%20d%20y%20d%20x)
M=y e^{x}
Therefore
x -->0 to 4
y --> 0 to 3
In conclusion, the line integral along the given positively oriented curve.
![=3\left[e^{4}-1\right]](https://tex.z-dn.net/?f=%3D3%5Cleft%5Be%5E%7B4%7D-1%5Cright%5D)

Answer:x=7& y= 2
Step-by-step explanation:
x+3y=13
3x+2y=25
Using elimination method
We have
3× x+3y=13......I
1×3x+2y=25....ii
3x+9y=39
3x+2y=25
7y=14
Divide through by 7
y=2
Substitute for y in equation i
x+3(2)=13
x+6=13
x=7
