Sin² x + sin x cos x = 0
sin x ( sin x + cos x ) = 0
sin x = 0 ; x 1 = k π ; k ∈ Z
sin x + cos x = 0 / ²
sin² x + 2 sin x cos x + cos² x = 0
2 sin x cos x + 1 =0
sin ( 2 x ) = - 1
x = 3π / 2 + 2 kπ / : 2
x 2 = 3π / 4 + kπ ; k ∈ Z
Answer:
$12.95 is the final cost for the oranges
$12 is the cost for apple
Step-by-step explanation:
The final cost for the orange is
30/100 x 18.50

18.50-5.55
=$12.95
Answer:
x=7
Step-by-step explanation:
Opposite of subtraction is adding so you do 4+10=14 so that means that x equals seven because 2x7 equals 14.
-5, -4, 0, 2, 3. From smallest to largest
The answer is -3.25 is greater :)
