Answer:
6 units
Step-by-step explanation:
JK + KL = JL
3x + 5x-6 = 4x+2
8x-6 = 4x+2
subtract 4x from each side to get:
4x - 6 = 2
add 6 to each side to get:
4x = 8
x = 2
JK = 3x and x=2 so JK = (3)(2) or 6
W=-L+P/2
subtract L to the other side and then diving everything by 2 to get W by itself
Answer:
3x10, 6x5
Step-by-step explanation:
45 / 1.5 = 30
Find any two factors of 30 and you have an answer.
2x15 and 1x30 don't work because they are less than or equal to 2.
Answer:
Step-by-step explanation:
3 sinθ=3 cos 2θ
sin θ=cos 2θ
sinθ=1-2sin² θ
2sin²θ+sin θ-1=0
2sin²θ+2sinθ-sinθ-1=0
2sin θ(sin θ+1)-1(sin θ+1)=0
(sin θ+1)(2 sin θ-1)=0
sin θ=-1=-sin 90=sin (180+90)
θ=270
or sin θ=1/2=sin 30,sin (180-30)
θ=30,150
solution set is {30,150,270}
