Answer:
1. Karen= g^5 (not sure)
2. Mike = g^5 + 3 (not sure)
3. Karen = 25
Mike = 28
4. Karen = 35
Mike = 38
Step-by-step explanation:
1. if george age was g
karen age= g x 5 = g5
2. mike age= gx5 + 3
3. g = 5
karen age= 5 x 5 = 25
mike 25 + 3
4. g = 7
karen = 7x5 = 35
mike = 35 + 3

Focus on triangles DFC and DFE:
- They are both right triangles because DF is perpendicular to EC
So, the two triangles are congruent. It follows that CF=FE, and in particular

And since x=3, the length of EF is

Answer:
C
Step-by-step explanation:
The general rule is that any 2 must exceed the third in order for a triangle to form. If any one is an exception, it won't work.
A will form a triangle. Any 2 exceeds the third.
B also forms a triangle. Same rule.
C does not work. 7 + 11 = 18 which is the value of the third leg.
D words Any two exceeds the 3rd.
