Answer:
3) a<5
5) z≤2
Step-by-step explanation:
3) a/5<1
a<1x5
a<5
5) 5(z+6)≤40
5z+30≤40
5z≤40-30
5z≤10
z≤10÷5
z≤2

In order to figure this out you need to use
Descartes Rule. I attached a picture showing Descartes Rule. If the signs changes for when x is positive then the number of times it changes are the possible positive solution. If the sign changes when x is negative then the number of times it changes are the possible negative solutions. With that said the answer is A. View the picture I have attached for the possible + - and imaginary solutions.
Answer = A) One possible positive solution.
Yes you can assume they are similar because the sides that correspond with one another are half of the big triangles measurements. 16/2=8 12/2=6 etc.
