PLEASE HELPPPP!!!!!!

Sloan [31]

Step-by-step explanation:

y=kx

say that y is the original prince and x is the sale price

15=k(10)

15/10=k

3/2=k

you can check with the next problem to check if it is the same

25=k(20)

25/20=k

5/4=k

so you take 5/4-3/2=-1/4 so the constant is -1/4

Hope that helps :)

Find the perimeter of the triangle in units. Round to two decimal places as necessary.

Dimas [21]

Answer:

54.56 units

Step-by-step explanation:

The vertices are:

K(-12,2), L(-7,12), J(3,-10)

Find the sides using distance formula:

KL = $\sqrt{(-7+12)^2+(12-2)^2} = \sqrt{125}$ ≈ 11.18
LJ = $\sqrt{(3+7)^2+(-10-12)^2} = \sqrt{584}$ ≈ 24.17
KJ = $\sqrt{(3+12)^2+(-10-2)^2} = \sqrt{369}$ ≈ 19.21

Find perimeter:

P = KL + LJ + KJ
P = 11.18 + 24.17 + 19.21 = 54.56 units

$\bf \sqrt{75x^5y^8}\qquad 
\begin{cases}
75=3\cdot 25\\
\qquad 3\cdot 5^2\\
x^5=x^{4+1}\\
\qquad x^4x^1\\
\qquad (x^2)^2x\\
y^8=y^{4\cdot 2}\\
\qquad (y^4)^2
\end{cases}\implies \sqrt{3\cdot 5^2\cdot (x^2)^2x(y^4)^2}
\\\\\\
5x^2y^4\sqrt{3x}$
