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
Answer:
11 79/80
Step-by-step explanation:
2+4+3+ 3/4+4/5+8/9
=9+ 3(5*9) +4(4*9) + 8(5*4)/4*5*9
=9 + 135+ 144+160/180
=9+ 439/180
=9+2 + 79/80
=11 79/80
25)divide by 3/8 on both sides
26) divide by 21 both sides
Circumference = 2 * PI * radius
Circumference = 2 * 3.14159265 * 63
Circumference = 395.841
Answer:
The answer should be 3 :)
Step-by-step explanation:
Pick a point on f(x) and count up until you hit the g(x) point :)
When i did this, i got 3 :)
Have an amazing day!!
