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).
Answer:1 and 1/4
Step-by-step explanation:
Okay, let's see the given: 20/16
So, we can take out 16 from the top to make it 1 4/16
Now, we can simplify that by dividing the top and bottom by 2: 1 2/8
We can simplify that again to get 1 1/4
So the answer is 1 and 1/4
(b - 4z)/7 = a
b - 4z = 7a
b = 7a + 4z
Answer: b = 7a + 4z
