A is the same because the value isn't changed and values are just switched not changes therefore meaning that "a" is right
First get rid of the last set of () by doing distributive property with the - sign
x^2 + 2x -1 - x^2 + 2x -1
=4x - 2
First, find the slope of this line, if possible. Recall that slope = m = rise / run.
We see that x does not change:
the distance from 2 to 2 is 0, and thus the slope of this line would be undefined, due to division by zero. Thus, the line is vertical. if it passes thru (2,3), then the equation of the line can be taken to be x=2.
The answer is 10, so it would be C
Answer: Dimensions are given as below:
Length = 236 yards
width = 144 yards
Step-by-step explanation:
Let the width be x
then length = 92 more than x = 92+x
formula for perimeter of rectangle = 2 [ length + width]
therefore
760 = 2 [ 92+x + x ]
760 = 2 ( 92+2x )
760 = 184 + 4x
4x = 760 - 184
4x = 576
x= 
=
x = 144
So width = 144 yards
Length = 144+92 = 236 yards
