The point-slope form:

m - slope
We have the slope m = 2 and the point (6, 1). Substitute:

Answer: E and D
Step-by-step explanation: E (SAS) allows you to find the other two angle measures and the last side length. D (ASA) lets you find the other angle and the other side lengths. The rest of the answers either don't account for both angles and sides, or don't give sufficient information.
Answer:
AC = 28 feet
Step-by-step explanation:
Point C is the midpoint of AB, so AC is half the length of AB:
AB/2 = (56 ft)/2 = 28 ft = AC
Answer:
Perimeter of the rectangle=6x+8 square units
Step-by-step explanation:
Given that area of rectangle is 
Area of rectangle=lw square units




Comparing the above equation with the given area we get
lw=(x+3)(2x+1)
Therefore length=x+3 and width=2x+1
To find the perimeter :
Perimeter of the rectangle=2(l+w) square units




Therefore perimeter of the rectangle=6x+8 square units
