Ok so first u have to devide the 51 into 4. So 51 divided by 4 is 12.75. Then it is 75% of it so 75% is 3/4 so you will have to multiply 12.75 by 3. That would equal 38.25. YOUR ANSWER IS 38.25
0.99999696 is your answer I am pretty sure.
Answer:
2 your welcome
Step-by-step explanation:
Answer:
If you've learnt sin(A+B) = sinAcosB + cosAsinB,
sin(4u)
= sin(2u+2u)
= sin(2u)cos(2u) + cos(2u)sin(2u)
= 2 sin(2u) cos(2u).
You add 2x and 7x to get 9x
so the answer is 9x+5y
