Answer:
y= -3/2x+9
Step-by-step explanation:
Well we have to know that to find a line perpendicular to a given line, you have to have opposite slopes. So that makes the equation begin as y=-3/2x because it's opposite of y=2/3x. Then we have to make sure it goes through the point (4,3). To do that, I tweaked the numbers in my graphing calculator and it worked with 9! So the equation is y= -3/2x+9
The perimeter of the square is 48
There are 4 equal-length sides to the square, making each side 12 in. in length
to find the area, multiply two sides of the perimeter
12 x 12 = 144
Perimeter: 48
Side: 12
Area: 144

14^2 - 9^2 = a^2
Easy enough
14^2 = 196
9^2 = 81
196 - 81 = 115
The square root of 115 = 10.72
The third side is 10.72km
I think it is D the answer choose
