I’m not sure but u multiply 2.5 by 3.8 to get amount she has to pay for GB. Since it free texts so 2.5 • 3.8 = $9.5 plus $15 which give $24.5
I could be wrong..
Parallel lines are always straight so find the coordinates and then do y2-y1 over x2-x1 and it will be 0
If 48/64 are both divided by 8 you would get 6/8! these can still be reduced to 3/4, So FALSE!
Answer:
The first one is correct
Step-by-step explanation:
You can multiply the base and perpendicular height to find the area.
Hello !
cos (a+b) = cos a cos b - sin a sin b
sin (a+b) = sin a cos b + sin b cos a
cos (a+b+c) = cos (a+(b+c))
cos (a+b+c) = cos a cos (b+c) - sin a sin (b+c)
cos (a+b+c) = cos a (cos b cos c - sin b sin c) - sin a (sin b cos c + sin c cos b)
cos (a+b+c)=cos a cos b cos c - cos a sin b sin c - sin a sin b cos c - sin a cos b sin c
