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:
what this is so confusing
Answer:
20
Step-by-step explanation:
c= 1.5q + 6 = 36
1.5q = 30. ( -6)
q = 20 (30/1.5)
Answer:
k=70
Step-by-step explanation:
two ways to do this
the sum of k+110 has to equal 180, so k=70
52+58+k has to equal 180, so k=70
1. It is the product of a square, meaning it can be simplified to (x+10)(x+10) or (x+10)^2
