Hello,

First equation: (2x^(3)+4x-8)+(-6x^(3)-7x+4)

Combine like terms : -4x^(3) - 3x - 4

Second equation: (2x^(2)+4x-8)-(-6x^(2)-7x+2)

Combine like terms: 8x^(2) + 11x - 10

How do I find the distance between (-2,5) and (22,12)
jok3333 [9.3K]

\bf ~~~~~~~~~~~~\textit{distance between 2 points} \\\\ (\stackrel{x_1}{-2}~,~\stackrel{y_1}{5})\qquad (\stackrel{x_2}{22}~,~\stackrel{y_2}{12})\qquad \qquad d = \sqrt{( x_2- x_1)^2 + ( y_2- y_1)^2} \\\\\\ d=\sqrt{[22-(-2)]^2+[12-5]^2}\implies d=\sqrt{(22+2)^2+(12-5)^2} \\\\\\ d=\sqrt{24^2+7^2}\implies d=\sqrt{625}\implies d=25

Alice's backyard is a rectangular piece of property that is twice as long as it is wide. The total area of her yard is 500 m^(2)
Alchen [17]
The approximate width of Alice's backyard is 22.36 in.

Let l be the length of the rectangle and w be the width.
l = 2w
A = 1000 m2 = l*w
1000 m2 = 2w *w
500 m2 = w^2
√500 m2 = √w^2
w = <span>22.360679775 in or 22.36 in</span>
