A(-5,5)
B(4,5)
C(2,0)
D(-5,-2)

AB,BC,CD,DA

AB = [4-(-5)),5-5]=[9,0]
Lenght  AB= \sqrt{9^2+0^2}= \sqrt{81}  =9

BC = [2-4,0-5]=[-2,-5]
Lenght  BC=\sqrt{(-2)^2+(-5)^2}=\sqrt{4+25}=\sqrt{29}

CD = [-5-2,-2-0]=[-7,-2]
Lenght  CD=\sqrt{(-7)^2+(-2)^2}=\sqrt{49+4}=\sqrt{53}

DA =[-5-(-5),-2-5]=[0,-7]
Lenght DA=\sqrt{0^2+(-7)^2}=\sqrt{49}=7

sorted from longest to shortest:
AB, CD,DA,BC
\sqrt{81}, \sqrt{53}, \sqrt{49}, \sqrt{29}

Simplify 8x^4/x^3+7x^4 and Find the excluded values​
Maksim231197 [3]

So first what we do is we need to get the excluded values. So to get them we have: 8x^4/x^3+7x^4.

Lets factor out the second part. x^3+7x^4 = (x^(3/4)+7x))^4

So then we get 8x^4/(x^(3/4)+7x)^4

8x^4/(x^(3/4)+7x)^4

Answer:

Step-by-step explanation:

Notice they both have the same slope of 3x so they are parallel, but different y intercepts. This means the lines never intersect and thus there are no solutions to the system of equations.
