7/8 remains the same
3/4 multiply the top and bottom by 2 so
3*2=6
4*2=8
so its so 6/8
Answer:
x = 3π/4, 5π/4
Step-by-step explanation:
cos(x+2π) = -√2/2, [0,2π]
cos(x)cos(2π)-sin(x)sin(2π) = -√2/2
cos(x) = -√2/2
x = 3π/4, 5π/4
Remember that the cosine function is periodic, so cos(θ+2π)=cos(θ).
D=(S+8)/C
S=DC-8
add 8 to both sides
S+8=DC
divide c from both sides
(S+8)/C=D
Answer:
6
Step-by-step explanation:
6*4=24
1/2*24=12
3+2=5
