Its the last one, the shapes but be polygons.
You were right, its the second choice CA=CB+BA
Answer:
the slope is 1/2
Work:
if the x-coordinate is two times the y-coordinate, that means you are going up one over two each time
slope= y2-y1/x2-x1
so you can pick two points, like (2, 1) and (4,2) and use the formula
slope= 2-1/4-2= 1/2
Answer:
therefore the side of the square is 2x + 5.
Step-by-step explanation:
i) let the side of the square be a
ii) therefore the perimeter of the square = 4a
iii) therefore 4a = 8x + 20
iv) therefore a = 2x + 5
therefore the side of the square is 2x + 5.
