Answer:
a) 3/2 or 1.5
b) 2/3 or ≈.66
Step-by-step explanation:
AB corresponds to DE because they are both the longest sides of their respective triangles.
a) The scale factor would be what you would multiply 8 by to get 12. 12/8 is 3/2 or 1.5
b) The scale factor would be what you multiply 12 by to get 8. 8/12 is 2/3 or ≈.66
Answer: 18/80=0.225
Step-by-step explanation:
What I like to in these problems is the grouping method. Split it into x^3-5x^2 .... 6x-30. Then factor so x^2 (x-5) and 6 (x-5). Now that both are factored put the coefficients together and use (x-5). This means that you have (x^2+6) and (x-5). Solve and your zeroes are + and - root 6 and 5.
Answer:
80% increase
Step-by-step explanation:
