Answer:
A=30cm, B=39cm
Step-by-step explanation:
They are an enlargement. Therefore, the sides are larger by the same proportion, otherwise, it wouldn't be an enlargement. Therefore, the bottom side of the big one is 3 times that of the small one. Therefore, the other sides are also 3 times, making A = 30cm and B = 39cm.
Id d because to get it it order of emlimination
Is there any extra information in the question?
Here the solution in in picture.
(f/g)(8)=f(8)/g(8)
find f(8) and g(8) to mke it easier
f(8)=3-(8)=3-2(8)=3-16=-13
g(8)=1/(5+8)=1/13
so (f/g)(8)=-13/(1/13)=-13*13=-169
answer is -169
