Answer: The correct answer is c.
Step-by-step explanation:
You take the area of the square which is 20x20 = 400.
There is 5 squares 400x5 = 2000
There is 4 triangles--which is 1/2 the area of 1 square (In this case).
One triangle = 200
200x4 = 800
2000 + 800 = 2800
Answer:
(a)
(b)
(c)
Solving (a):
Take LCM
Multiply through by 20
Solve for x
Solving (b):
This gives:
Solving (c):
Multiply both sides by
(7,0)
v(-2) = 11, v(0) = 7, v(5) = -3.
hope this helps! :)
