Sin 2 x + 2 sin x = 0
2 sin x cos x + 2 sin x = 0 / : 2
sin x cos x + sin x = 0
sin x ( cos x + 1 ) = 0
sin x = 0, cos x + 1 = 0, cos x = - 1;
Answer:
x = 0, or x = π
Answer:easy thats C

Small problem....
There is no graph!
ill be happy to solve this if i saw a graph
Radius is just half of a diameter. and you just multiply the diameter by pi for circumference.
so here, it would be 35x2 x 22/7 so the answer is 220 CM
Answer:
x=10 or x=-2
Step-by-step explanation:
add 28 to both sides
(x-4)^2=36
sqrt both sides
remember to get positive and negative roots
x-4=+/-6
add 4 to both sides
x=4+/-6
x=4+6 or x=4-6
