Answer:
you draw a straight line at question 7, but you cannot draw a straight line at 9, so 9 cannot be linear
Step-by-step explanation:
Answer:
A lizard is an animal but doesn't have fur.
Step-by-step explanation:
A counterexample would be to give an example of an animal that doesn't have fur. So the premise is met: there is a clear example of what one considers an animal, but the animal doesn't have fur.
For example a lizard is clearly an animal, but it doesn't have fur around its body. One needs to just find one example that negates the given statement to make it false.

Answer: 6</h3>
===========================================================
Work Shown:
(whole length)*(external part) = (whole length)*(external part)
(EG)*(FG) = (SG)*(HG)
(2x+4)*(4) = (x+5)*(5)
8x+16 = 5x+25
8x-5x = 25-16
3x = 9
x = 9/3
x = 3
Use this x value to find EF
EF = 2x
EF = 2*3
EF = 6
