Answer:
C
Step-by-step explanation:
Rmember (a/b)/(c/d)=(a/b)(d/c)=(ad)/(bc)this is just alot of busy work
find f+g first then find f-g
f+g=(x-4)/(x+9)+(x-9)/(x+4)
make denomenator the same
multiply left one by (x+4)/(x+4) and right one by (x+9)/(x+9)
[(x-4)(x+4)]/[(x+9)(x+4)]+[(x-9)(x+9)]/[(x+9)(x+4)]
[x²-16]/[(x+9)(x+4)]+[x²-81]/[(x+9)(x+4)]
[x²+x²-16-81]/[(x+9)(x+4)]
[2x²-97]/[(x+9)(x+4)]
now f-g
[x²-16]/[(x+9)(x+4)]-[x²-81]/[(x+9)(x+4)]
[x²-x²-16+81]/[(x+9)(x+4)]
[65]/[(x+9)(x+4)]
now we got
invert and multiply
2nd option
You seem to have forgotten to show the inequality! Can you try again?
Answer:
65
Step-by-step explanation:
The first base matches the second height
The second base matches the first height
The third base matches the third height
<h3>Base and height of a triangle </h3>
From the question, we are to match the base to the corresponding height
In a triangle, the height of the triangle is perpendicular to the base.
Applying this in the given diagram,
The first base matches the second height
The second base matches the first height
The third base matches the third height
